Sets the signature body of the message to the passed $body for a multipart/signed message.
setTextPart()  : static
Sets the text/plain part of the message to the passed $resource, either creating a new part if one doesn't exist for text/plain, or assigning the value of $resource to an existing text/plain part.

public __toString() : string

Convenience method for calling getContents() on IMessagePart::getStream().

Return values
string —

addAttachmentPart()

Adds an attachment part for the passed raw data string, handle, or stream and given parameters.

public addAttachmentPart(mixed $resource, string $mimeType[, string|null $filename = null ][, string $disposition = 'attachment' ][, string $encoding = 'base64' ]) : static

Note that $disposition must be one of 'inline' or 'attachment', and will default to 'attachment' if a different value is passed.

Parameters
$resource : mixed

the part's content

$mimeType : string

the mime-type of the attachment

$filename : string|null = null

Optional filename (to set relevant header params)

$disposition : string = 'attachment'

Optional Content-Disposition value.

$encoding : string = 'base64'

defaults to 'base64', only applied for a mime email

Return values
static —

addAttachmentPartFromFile()

Adds an attachment part using the passed file.

public addAttachmentPartFromFile(string $filePath, string $mimeType[, string|null $filename = null ][, string $disposition = 'attachment' ][, string $encoding = 'base64' ]) : static

Essentially creates a psr7 stream and calls IMessage::addAttachmentPart.

Note that $disposition must be one of 'inline' or 'attachment', and will default to 'attachment' if a different value is passed.

Parameters
$filePath : string

file to attach

$mimeType : string

the mime-type of the attachment

$filename : string|null = null

Optional filename (to set relevant header params)

$disposition : string = 'attachment'

Optional Content-Disposition value.

defaults to 'base64', only applied for a mime email

Return values
static —

addChild()

Registers the passed part as a child of the current part.

public addChild(MessagePart $part[, int|null $position = null ]) : static

If the $position parameter is non-null, adds the part at the passed position index, otherwise adds it as the last child.

Parameters
$part : MessagePart

The part to add.

$position : int|null = null

Optional insertion position 0-based index.

Return values
static —

addError()

Creates and adds an Error object to this ErrorBag.

public addError(string $message, string $psrLogLevel[, Throwable|null $exception = null ]) : static

Return values
static —

addRawHeader()

Adds a header with the given $name and $value.

public addRawHeader(string $name, string $value) : static

Note: If a header with the passed name already exists, a new header is created with the same name. This should only be used when that is intentional - in most cases IMimePart::setRawHeader() should be called instead.

A new IHeader object is created from the passed value. No processing on the passed string is performed, and so the passed name and value must be formatted correctly according to related RFCs. In particular, be careful to encode non-ascii data, to keep lines under 998 characters in length, and to follow any special formatting required for the type of header.

Parameters
$name : string

The name of the header

$value : string

The raw value of the header.

Return values
static —

attach()

public attach(SplObserver $observer) : void
Parameters
$observer : SplObserver
Return values
void —

attachContentStream()

public attachContentStream(StreamInterface $stream[, string $streamCharset = MailMimeParser::DEFAULT_CHARSET ]) : static
Parameters
$stream : StreamInterface

the content

$streamCharset : string = MailMimeParser::DEFAULT_CHARSET

the charset of $stream

Return values

detachContentStream()

Detaches the content stream.

public detachContentStream() : static
Return values
static —

from()

Convenience method to parse a handle or string into an IMessage without requiring including MailMimeParser, instantiating it, and calling parse.

public static from(resource|StreamInterface|string $resource, bool $attached) : IMessage

If the passed $resource is a resource handle or StreamInterface, the resource must remain open while the returned IMessage object exists. Pass true as the second argument to have the resource attached to the IMessage and closed for you when it's destroyed, or pass false to manually close it if it should remain open after the IMessage object is destroyed.

Parameters
$resource : resource|StreamInterface|string

The resource handle to the input stream of the mime message, or a string containing a mime message.

$attached : bool

pass true to have it attached to the returned IMessage and destroyed with it.

Return values
IMessage —

getAllAttachmentParts()

Returns all attachment parts.

public getAllAttachmentParts() : array<string|int, IMessagePart>

The method returns all parts other than the main content part for a non-mime message, and all parts under a mime message except:

  • text/plain and text/html parts with a Content-Disposition not set to 'attachment'
  • all multipart/* parts
  • any signature part
Return values
array<string|int, IMessagePart> —

getAllErrors()

Returns any errors on this object, and all IErrorBag children of this object at or above the passed PSR log level from Psr\Log\LogLevel (defaulting to LogLevel::ERROR).

public getAllErrors([bool $validate = false ][, string $minPsrLevel = LogLevel::ERROR ]) : array<string|int, Error>

Care should be taken using this if the intention is to only 'preview' a message without parsing it entirely, since this will cause the whole message to be parsed as it traverses children, and could be slow on messages with large attachments, etc...

If $validate is true, additional validation may be performed on children to check for errors.

Parameters
$validate : bool = false
$minPsrLevel : string = LogLevel::ERROR
Return values
array<string|int, Error> —

getAllHeaders()

Returns an array of all headers in this part.

public getAllHeaders() : array<string|int, IHeader>
Return values
array<string|int, IHeader> —

an array of header objects

getAllHeadersByName()

Returns an array of headers that match the passed name.

public getAllHeadersByName(string $name) : array<string|int, IHeader>
Parameters
$name : string
Return values
array<string|int, IHeader> —

an array of header objects

getAllParts()

Returns the current part, all child parts, and child parts of all children optionally filtering them with the provided PartFilter.

public getAllParts([callable|null $fnFilter = null ]) : array<string|int, IMessagePart>

Note that the first part returned is the current part itself. This is often desirable for queries with a passed filter, e.g. looking for an IMessagePart with a specific Content-Type that may be satisfied by the current part.

The passed callable must accept an IMessagePart as an argument, and return true if it should be accepted, or false to filter the part out. Some default filters are provided by static functions returning callables in PartFilter.

Parameters
$fnFilter : callable|null = null

Optional function accepting an IMessagePart and returning true if the part should be included.

Return values
array<string|int, IMessagePart> —

An array of matching parts.

getAllPartsByMimeType()

Returns an array of all parts that have a content type matching the passed mime type.

public getAllPartsByMimeType(string $mimeType) : array<string|int, IMessagePart>

Creates a filter that looks at the return value of IMessagePart::getContentType() for all parts (including the current part), returning an array of matching parts.

Parameters
$mimeType : string

The mime type to find.

Return values
array<string|int, IMessagePart> —

An array of matching parts.

getAttachmentCount()

Returns the number of attachments available.

public getAttachmentCount() : int

public getAttachmentPart(int $index) : IMessagePart|null

The method returns all parts other than the main content part for a non-mime message, and all parts under a mime message except:

  • text/plain and text/html parts with a Content-Disposition not set to 'attachment'
  • all multipart/* parts
  • any signature part
Parameters
$index : int

the 0-based index of the attachment part to return.

Return values

getBinaryContentResourceHandle()

Returns a resource handle for the content's raw data stream, or null if the part doesn't have a content stream.

public getBinaryContentResourceHandle() : resource|null

The method wraps a call to IMessagePart::getBinaryContentStream() and returns a resource handle for the returned Stream.

Return values
resource|null —

the resource

getBinaryContentStream()

Returns the raw data stream for the current part, if it exists, or null if there's no content associated with the stream.

public getBinaryContentStream() : StreamInterface|null

This is basically the same as calling IMessagePart::getContentStream(), except no automatic charset conversion is done. Note that for non-text streams, this doesn't have an effect, as charset conversion is not performed in that case, and is useful only when:

  • The charset defined is not correct, and the conversion produces errors; or
  • You'd like to read the raw contents without conversion, for instance to save it to file or allow a user to download it as-is (in a download link for example).
Return values
StreamInterface|null —

the stream

getCharset()

Returns the charset of the content, or null if not applicable/defined.

public getCharset() : string|null

Looks for a 'charset' parameter under the 'Content-Type' header of this part and returns it if set, defaulting to 'ISO-8859-1' if the Content-Type header exists and is of type text/plain or text/html.

Note that the returned value is also converted to upper case.

Return values
string|null —

the charset

getChild()

Returns the direct child at the given 0-based index and optional filter, or null if none exist or do not match.

public getChild(int $index[, callable|null $fnFilter = null ]) : IMessagePart|null

The passed callable must accept an IMessagePart as an argument, and return true if it should be accepted, or false to filter the part out. Some default filters are provided by static functions returning callables in PartFilter.

Parameters
$index : int

0-based index

$fnFilter : callable|null = null

Optional function accepting an IMessagePart and returning true if the part should be included.

Return values
IMessagePart|null —

The matching direct child part or null if not found.

getChildCount()

Returns the number of direct children under this part (optionally counting only filtered items if a callable filter is passed).

public getChildCount([callable|null $fnFilter = null ]) : int

The passed callable must accept an IMessagePart as an argument, and return true if it should be accepted, or false to filter the part out. Some default filters are provided by static functions returning callables in PartFilter.

Parameters
$fnFilter : callable|null = null

Optional function accepting an IMessagePart and returning true if the part should be included.

Return values
int —

The number of children, or number of children matching the the passed filtering callable.

getChildParts()

Returns an array of all direct child parts, optionally filtering them with a passed callable.

public getChildParts([callable|null $fnFilter = null ]) : array<string|int, IMessagePart>

The passed callable must accept an IMessagePart as an argument, and return true if it should be accepted, or false to filter the part out. Some default filters are provided by static functions returning callables in PartFilter.

Parameters
$fnFilter : callable|null = null

Optional function accepting an IMessagePart and returning true if the part should be included.

Return values
array<string|int, IMessagePart> —

An array of matching child parts.

getContent()

Shortcut to reading stream content and assigning it to a string. Returns null if the part doesn't have a content stream.

public getContent([string $charset = MailMimeParser::DEFAULT_CHARSET ]) : string|null

The returned string is encoded to the passed $charset character encoding.

Parameters
$charset : string = MailMimeParser::DEFAULT_CHARSET

the target charset for the returned string

Return values
string|null —

the content

getContentDisposition()

Returns the content's disposition, or returns the value of $default if not defined.

public getContentDisposition([string $default = 'inline' ]) : string

Looks at the 'Content-Disposition' header, which should only contain either 'inline' or 'attachment'. If the header is not one of those values, $default is returned, which defaults to 'inline' unless passed something else.

Parameters
$default : string = 'inline'

Optional default value if not set or does not match 'inline' or 'attachment'.

Return values
string —

the content disposition

getContentId()

Returns the Content ID of the part, or null if not defined.

public getContentId() : string|null

Looks up and returns the value of the 'Content-ID' header.

Return values
string|null —

the content ID or null if not defined.

getContentStream()

Returns the StreamInterface for the part's content or null if the part doesn't have a content section.

public getContentStream([string $charset = MailMimeParser::DEFAULT_CHARSET ]) : StreamInterface|null

To get a stream without charset conversion if you know the part's content contains a binary stream, call self::getBinaryContentStream() instead.

The library automatically handles decoding and charset conversion (to the target passed $charset) based on the part's transfer encoding as returned by IMessagePart::getContentTransferEncoding() and the part's charset as returned by IMessagePart::getCharset(). The returned stream is ready to be read from directly.

Note that the returned Stream is a shared object. If called multiple times with the same $charset, and the value of the part's Content-Transfer-Encoding header has not changed, the stream will be rewound. This would affect other existing variables referencing the stream, for example:

// assuming $part is a part containing the following
// string for its content: '12345678'
$stream = $part->getContentStream();
$someChars = $part->read(4);

$stream2 = $part->getContentStream();
$moreChars = $part->read(4);
echo ($someChars === $moreChars);    //1

In this case the Stream was rewound, and $stream's second call to read 4 bytes reads the same first 4.

Parameters
$charset : string = MailMimeParser::DEFAULT_CHARSET

Optional charset for the returned stream.

Return values
StreamInterface|null —

the stream

getContentTransferEncoding()

Returns the content transfer encoding used to encode the content on this part, or the value of $default if not defined.

public getContentTransferEncoding([string $default = '7bit' ]) : string

Looks up and returns the value of the 'Content-Transfer-Encoding' header if set, defaulting to '7bit' if an alternate $default param is not passed.

The returned value is always lowercase, and header values of 'x-uue', 'uue' and 'uuencode' will return 'x-uuencode' instead.

Parameters
$default : string = '7bit'

Optional default value to return if the header isn't set.

the content transfer encoding.

getContentType()

Returns the mime type of the content, or $default if one is not set.

public getContentType([string $default = 'text/plain' ]) : string

the file name

getHeader()

Returns the IHeader object for the header with the given $name.

public getHeader(string $name, int $offset) : IHeader|null

If the optional $offset is passed, and multiple headers exist with the same name, the one at the passed offset is returned.

Note that mime header names aren't case sensitive, and the '-' character is ignored, so ret

getHtmlContent()

Returns the content of the inline text/html part as a string.

public getHtmlContent(int $index[, string $charset = MailMimeParser::DEFAULT_CHARSET ]) : string|null

If the message contains more than one text/html 'inline' part, the default behavior is to return the first part. The content for additional parts can be returned by passing a 0-based index.

If a part at the passed index doesn't exist, null is returned.

Parameters
$index : int

Optional 0-based index of inline html part content.

Returns the part at the given 0-based index for this part (part 0) and all parts under it, or null if not found with the passed filter function.

public getPart(int $index[, callable|null $fnFilter = null ]) : IMessagePart|null

Note that the first part returned is the current part itself. This is usually desirable for queries with a passed filter, e.g. looking for an part with a specific Content-Type that may be satisfied by the current part.

The passed callable must accept an IMessagePart as an argument, and return true if it should be accepted, or false to filter the part out. Some default filters are provided by static functions returning callables in PartFilter.

Parameters
$index : int

The 0-based index (0 being this part if $fnFilter is null or this part is satisfied by the filter).

$fnFilter : callable|null = null

Optional function accepting an IMessagePart and returning true if the part should be included.

Return values
IMessagePart|null —

A matching part, or null if not found.

getPartByContentId()

Returns a part that has the given Content ID, or null if not found.

public getPartByContentId(string $contentId) : IMessagePart|null

Calls IMessagePart::getContentId() to find a matching part.

$contentId : string

The content ID to find a part for.

Return values
IMessagePart|null —

The matching part.

getPartByMimeType()

Returns the part that has a content type matching the passed mime type at the given index, or null if there are no matching parts.

public getPartByMimeType(string $mimeType, int $index) : IMessagePart|null

Creates a filter that looks at the return value of IMessagePart::getContentType() for all parts (including the current part) and returns a matching one at the given 0-based index.

Parameters
$mimeType : string

The mime type to find.

$index : int

Optional 0-based index (defaulting to '0').

Return values
IMessagePart|null —

The part.

getPartCount()

Returns the total number of parts in this and all children.

public getPartCount([callable|null $fnFilter = null ]) : int

Note that the current part is considered, so the minimum getPartCount is 1 without a filter.

The passed callable must accept an IMessagePart as an argument, and return true if it should be accepted, or false to filter the part out. Some default filters are provided by static functions returning callables in PartFilter.

Parameters
$fnFilter : callable|null = null

Optional function accepting an IMessagePart and returning true if the part should be included.

Return values
int —

The number of matching parts.

getRawHeaderIterator()

Returns an iterator to all headers in this part. Each returned element is an array with its first element set to the header's name, and the second to its raw value:

public getRawHeaderIterator() : Traversable<string|int, array<string|int, string>>

[ 'Header-Name', 'Header Value' ]

Return values
Traversable<string|int, array<string|int, string>> —

an iterator for raw headers

getRawHeaders()

Returns a two dimensional string array of all headers for the mime part with the first element holding the name, and the second its raw string value:

public getRawHeaders() : array<string|int, array<string|int, string>>

[ [ '1st-Header-Name', 'Header Value' ], [ '2nd-Header-Name', 'Header Value' ] ]

Return values
array<string|int, array<string|int, string>> —

an array of raw headers

getResourceHandle()

Returns a resource handle for the string representation of this part, containing its headers, content and children. For an IMessage, this would be the entire RFC822 (or greater) email.

public getResourceHandle() : resource

If the part has not been modified and represents a parsed part, the original stream should be returned. Otherwise a stream representation of the part including its modifications should be returned. This insures that an unmodified, signed message could be passed on that way even after parsing and reading.

The returned stream is not guaranteed to be RFC822 (or greater) compliant for the following reasons:

  • The original email or part, if not modified, is returned as-is and may not be compliant.
  • Although certain parts may have been modified, an original unmodified header from the original email or part may not be compliant.
  • A user may set headers in a non-compliant format.
Return values
resource —

the resource handle containing the part.

getSignaturePart()

Returns the signature part of a multipart/signed message or null.

public getSignaturePart() : IMessagePart|null

The signature part is determined to always be the 2nd child of a multipart/signed message, the first being the 'body'.

Using the 'protocol' parameter of the Content-Type header is unreliable in some instances (for instance a difference of x-pgp-signature versus pgp-signature).

Return values
IMessagePart|null —

getSignedMessageAsString()

Returns a string containing the entire body of a signed message for verification or calculating a signature.

public getSignedMessageAsString() : string|null

Non-CRLF new lines are replaced to always be CRLF.

Return values
string|null —

null if the message doesn't have any children

getSignedMessageStream()

Returns a stream that can be used to read the content part of a signed message, which can be used to sign an email or verify a signature.

public getSignedMessageStream() : StreamInterface|null

The method simply returns the stream for the first child. No verification of whether the message is in fact a signed message is performed.

Note that unlike getSignedMessageAsString, getSignedMessageStream doesn't replace new lines, and before calculating a signature, LFs not preceded by CR should be replaced with CRLFs.

Return values
StreamInterface|null —

null if the message doesn't have any children

getStream()

Returns a Psr7 StreamInterface for the string representation of this part, containing its headers, content and children.

public getStream() : StreamInterface

If the part has not been modified and represents a parsed part, the original stream should be returned. Otherwise a stream representation of the part including its modifications should be returned. This insures that an unmodified, signed message could be passed on that way even after parsing and reading.

The returned stream is not guaranteed to be RFC822 (or greater) compliant for the following reasons:

  • The original email or part, if not modified, is returned as-is and may not be compliant.
  • Although certain parts may have been modified, an original unmodified header from the original email or part may not be compliant.
  • A user may set headers in a non-compliant format.
Return values
StreamInterface —

the stream containing the part.

getSubject()

Returns the subject of the message, retrieved from the 'Subject' header, or null if the message has none set.

public getSubject() : string|null
Return values
string|null —

getTextContent()

Returns the content of the inline text/plain part as a string.

public getTextContent(int $index[, string $charset = MailMimeParser::DEFAULT_CHARSET ]) : string|null

If the message contains more than one text/plain 'inline' part, the default behavior is to return the first part. The content for additional parts can be returned by passing a 0-based index.

If a part at the passed index doesn't exist, null is returned.

Parameters
$index : int

Optional 0-based index of inline text part content.

$charset : string = MailMimeParser::DEFAULT_CHARSET

Optional charset for the returned string to be encoded in.

Return values
string|null —

getTextPart()

Returns the inline text/plain IMessagePart for a message.

public getTextPart(int $index) : IMessagePart|null

If the message contains more than one text/plain 'inline' part, the default behavior is to return the first part. Additional parts can be returned by passing a 0-based index.

If there are no inline text/plain parts in this message, null is returned.

Parameters
$index : int

Optional index of part to return.

Return values
IMessagePart|null —

getTextPartCount()

Returns the number of inline text/plain parts this message contains.

public getTextPartCount() : int
Return values
int —

getTextStream()

Returns a Psr7 Stream for the 'inline' text/plain content.

public getTextStream(int $index[, string $charset = MailMimeParser::DEFAULT_CHARSET ]) : StreamInterface|null

If the message contains more than one text/plain 'inline' part, the default behavior is to return the first part. The streams for additional parts can be returned by passing a 0-based index.

If a part at the passed index doesn't exist, null is returned.

Parameters
$index : int

Optional 0-based index of inline text part stream.

$charset : string = MailMimeParser::DEFAULT_CHARSET

Optional charset to encode the stream with.

Return values
StreamInterface|null —

hasAnyErrors()

Returns true if there are errors on this object, or any IErrorBag child of this object at or above the passed PSR log level in Psr\Log\LogLevel (defaulting to LogLevel::ERROR). Note that this will stop after finding the first error and return, so may be slightly more performant if an error actually exists over calling getAllErrors if only interested in whether an error exists.

public hasAnyErrors([bool $validate = false ][, string $minPsrLevel = LogLevel::ERROR ]) : bool

Care should be taken using this if the intention is to only 'preview' a message without parsing it entirely, since this will cause the whole message to be parsed as it traverses children, and could be slow on messages with large attachments, etc...

If $validate is true, additional validation may be performed to check for errors.

Parameters
$validate : bool = false
$minPsrLevel : string = LogLevel::ERROR
Return values
bool —

hasContent()

Returns true if the part contains a 'body' (content).

public hasContent() : bool
Return values
bool —

hasErrors()

Returns true if this object has an error in its error bag at or above the passed $minPsrLevel (defaults to ERROR). If $validate is true, additional validation may be performed.

public hasErrors([bool $validate = false ][, string $minPsrLevel = LogLevel::ERROR ]) : bool

The PSR levels are defined in Psr\Log\LogLevel.

Parameters
$validate : bool = false
$minPsrLevel : string = LogLevel::ERROR
Return values
bool —

isMime()

Returns true if the current part is a mime part.

public isMime() : bool

The message is considered 'mime' if it has either a Content-Type or MIME-Version header defined.

Return values
bool —

isMultiPart()

Returns true if this part's content type matches multipart/*

public isMultiPart() : bool
Return values
bool —

isSignaturePart()

Returns true if this part's parent is an IMessage, and is the same part returned by {@see IMessage::getSignaturePart()}.

public isSignaturePart() : bool
Return values
bool —

isTextPart()

Returns true if this part has a defined 'charset' on its Content-Type header.

public isTextPart() : bool

This may result in some false positives if charset is set on a part that is not plain text which has been seen. If a part is known to be binary, it's better to use IMessagePart::getBinaryContentStream() to avoid issues, or to call IMessagePart::saveContent() directly if saving a part's content.

Return values
bool —

notify()

public notify() : void
Return values
void —

removeAllHtmlParts()

Removes all text/html inline parts in this message.

public removeAllHtmlParts([bool $moveRelatedPartsBelowMessage = true ]) : bool

If the message contains a multipart/alternative part, the html parts are removed from below the alternative part only. If there is only one remaining part after that, it is moved up, replacing the multipart/alternative part.

If the multipart/alternative part further contains a multipart/related (or mixed) part which holds an inline html part, only parts from that child multipart are removed, and if the passed $moveRelatedPartsBelowMessage is true, any non-html parts are moved to be below the message directly (changing the message into a multipart/mixed message if need be).

For more control, call IMessagePart::removePart() with parts you wish to remove.

Parameters
$moveRelatedPartsBelowMessage : bool = true

Optionally pass false to remove related parts.

Return values
bool —

true on success

removeAllParts()

Removes all parts below the current part. If a callable filter is passed, removes only those matching the passed filter. The number of removed parts is returned.

public removeAllParts([callable|null $fnFilter = null ]) : int

Note: the current part will not be removed. Although the function naming matches getAllParts, which returns the current part, it also doesn't only remove direct children like getChildParts. Internally this function uses getAllParts but the current part is filtered out if returned.

Parameters
$fnFilter : callable|null = null

Optional function accepting an IMessagePart and returning true if the part should be included.

Return values
int —

The number of removed parts.

removeAllTextParts()

Removes all text/plain inline parts in this message.

public removeAllTextParts([bool $moveRelatedPartsBelowMessage = true ]) : bool

If the message contains a multipart/alternative part, the text parts are removed from below the alternative part only. If there is only one remaining part after that, it is moved up, replacing the multipart/alternative part.

If the multipart/alternative part further contains a multipart/related (or mixed) part which holds an inline text part, only parts from that child multipart are removed, and if the passed $moveRelatedPartsBelowMessage is true, any non-text parts are moved to be below the message directly (changing the message into a multipart/mixed message if need be).

For more control, call IMessagePart::removePart() with parts you wish to remove.

Parameters
$moveRelatedPartsBelowMessage : bool = true

Optionally pass false to remove related parts.

Return values
bool —

true on success

removeAttachmentPart()

Removes the attachment at the given index.

public removeAttachmentPart(int $index) : static

Attachments are considered to be all parts other than the main content part for a non-mime message, and all parts under a mime message except:

  • text/plain and text/html parts with a Content-Disposition not set to 'attachment'
  • all multipart/* parts
  • any signature part
Parameters
$index : int
Return values
static —

removeHeader()

Removes all headers from this part with the passed name.

public removeHeader(string $name) : static
Parameters
$name : string

The name of the header(s) to remove.

Return values
static —

removeHtmlPart()

Removes the text/html part of the message at the passed index if one exists (defaults to first part if an index isn't passed).

public removeHtmlPart(int $index) : bool

Returns true if a part exists at the passed index and has been removed.

Parameters
$index : int

Optional 0-based index of inline html part to remove.

Return values
bool —

true on success

removePart()

Removes the child part from this part and returns its previous position or null if it wasn't found.

public removePart(IMessagePart $part) : int|null

Note that if the part is not a direct child of this part, the returned position is its index within its parent (calls removePart on its direct parent).

This also means that parts from unrelated parts/messages could be removed by a call to removePart -- it will always remove the part from its parent if it has one, essentially calling php $part->getParent()->removePart(); .

Parameters
$part : IMessagePart

The part to remove

Return values
int|null —

The previous index position of the part within its old parent.

removeSingleHeader()

Removes a single header with the passed name (in cases where more than one may exist, and others should be preserved).

public removeSingleHeader(string $name, int $offset) : static
Parameters
$name : string

The name of the header to remove

$offset : int

Optional offset of the header to remove (defaults to 0 -- the first header).

Return values
static —

removeTextPart()

Removes the text/plain part of the message at the passed index if one exists (defaults to first part if an index isn't passed).

public removeTextPart(int $index) : bool

Returns true if a part exists at the passed index and has been removed.

Parameters
$index : int

Optional 0-based index of inline text part to remove.

Return values
bool —

true on success

save()

Writes a string representation of this part, including its headers, content and children to the passed file, resource, or stream.

public save(mixed $filenameResourceOrStream[, string $filemode = 'w+' ]) : static

If the part has not been modified and represents a parsed part, the original stream should be written to the file. Otherwise a stream representation of the part including its modifications should be written. This insures that an unmodified, signed message could be passed on this way even after parsing and reading.

The written stream is not guaranteed to be RFC822 (or greater) compliant for the following reasons:

  • The original email or part, if not modified, is returned as-is and may not be compliant.
  • Although certain parts may have been modified, an original unmodified header from the original email or part may not be compliant.
  • A user may set headers in a non-compliant format.

If the passed $filenameResourceOrStream is a string, it's assumed to be a filename to write to.

When passing a resource or Psr7 Stream, the resource is not closed, nor rewound after being written to.

Parameters
$filenameResourceOrStream : mixed

the file, resource, or stream to write to.

$filemode : string = 'w+'

Optional filemode to open a file in (if $filenameResourceOrStream is a string)

Return values
static —

saveContent()

Saves the binary content of the stream to the passed file, resource or stream.

public saveContent(mixed $filenameResourceOrStream) : static

Note that charset conversion is not performed in this case, and the contents of the part are saved in their binary format as transmitted (but after any content-transfer decoding is performed). IMessagePart::getBinaryContentStream() for a more detailed description of the stream.

If the passed parameter is a string, it's assumed to be a filename to write to. The file is opened in 'w+' mode, and closed before returning.

When passing a resource or Psr7 Stream, the resource is not closed, nor rewound.

Parameters
$filenameResourceOrStream : mixed
Return values
static —

setAsMultipartSigned()

Turns the message into a multipart/signed message, moving the actual message into a child part, sets the content-type of the main message to multipart/signed and adds an empty signature part as well.

public setAsMultipartSigned(string $micalg, string $protocol) : static

After calling setAsMultipartSigned, call getSignedMessageAsString to get the normalized string content to be used for calculated the message's hash.

Parameters
$micalg : string

The Message Integrity Check algorithm being used

$protocol : string

The mime-type of the signature body

Return values
static —

setCharsetOverride()

Overrides the default character set used for reading content from content streams in cases where a user knows the source charset is not what is specified.

public setCharsetOverride(string $charsetOverride[, bool $onlyIfNoCharset = false ]) : static

If set, the returned value from IMessagePart::getCharset() must be ignored during subsequent read operations and streams created out of this part's content.

Note that setting an override on an IMessage and calling getTextStream, getTextContent, getHtmlStream or getHtmlContent will not be applied to those sub-parts, unless the text/html part is the IMessage itself. Instead, IMessage::getTextPart() should be called, and setCharsetOverride called on the returned IMessagePart.

Parameters
$charsetOverride : string

the actual charset of the content.

$onlyIfNoCharset : bool = false

if true, $charsetOverride is used only if getCharset returns null.

Return values
static —

setContent()

Sets the content of the part to the passed string, resource, or stream.

public setContent(mixed $resource[, string $charset = MailMimeParser::DEFAULT_CHARSET ]) : static
Parameters
$resource : mixed

the content.

$charset : string = MailMimeParser::DEFAULT_CHARSET
Return values
static —

setHtmlPart()

Sets the text/html part of the message to the passed $resource, either creating a new part if one doesn't exist for text/html, or assigning the value of $resource to an existing text/html part.

public setHtmlPart(mixed $resource[, string $charset = 'UTF-8' ]) : static

The optional $contentTypeCharset parameter is the charset for the text/html part's Content-Type, not the charset of the passed $resource. $resource must be encoded in UTF-8 regardless of the target charset.

Parameters
$resource : mixed

UTF-8 encoded content.

$charset : string = 'UTF-8'
Return values
static —

setRawHeader()

Adds a header with the given $name and $value. An optional $offset may be passed, which will overwrite a header if one exists with the given name and offset only. Otherwise a new header is added. The passed $offset may be ignored in that case if it doesn't represent the next insert position for the header with the passed name... instead it would be 'pushed' on at the next position.

public setRawHeader(string $name, string|null $value, int $offset) : static 
$part = $myMimePart;
$part->setRawHeader('New-Header', 'value');
echo $part->getHeaderValue('New-Header');        // 'value'

$part->setRawHeader('New-Header', 'second', 4);
echo is_null($part->getHeader('New-Header', 4)); // '1' (true)
echo $part->getHeader('New-Header', 1)
     ->getValue();                               // 'second'

A new IHeader object is created from the passed value. No processing on the passed string is performed, and so the passed name and value must be formatted correctly according to related RFCs. In particular, be careful to encode non-ascii data, to keep lines under 998 characters in length, and to follow any special formatting required for the type of header.

Parameters
$name : string

The name of the new header, e.g. 'Content-Type'.

$value : string|null

The raw value of the new header.

$offset : int

An optional offset, defaulting to '0' and therefore overriding the first header of the given $name if one exists.

Return values
static —

setSignature()

Sets the signature body of the message to the passed $body for a multipart/signed message.

public setSignature(string $body) : static
Parameters
$body : string

the message's hash

Return values
static —

setTextPart()

Sets the text/plain part of the message to the passed $resource, either creating a new part if one doesn't exist for text/plain, or assigning the value of $resource to an existing text/plain part.

public setTextPart(mixed $resource[, string $charset = 'UTF-8' ]) : static

The optional $contentTypeCharset parameter is the charset for the text/plain part's Content-Type, not the charset of the passed $resource. $resource must be encoded in UTF-8 regardless of the target charset.

Parameters
$resource : mixed

UTF-8 encoded content.

$charset : string = 'UTF-8'
Return values
static —

getErrorBagChildren()

Return any children ErrorBag objects.
