Methods

addAttachmentPart()

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

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

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

Parameters
$resource : string|resource|StreamInterface

the part's content

$mimeType : string

the mime-type of the attachment

$filename : string = 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
mixed

addAttachmentPartFromFile()

Adds an attachment part using the passed file.

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

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

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
mixed

addChild()

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

public addChild(IMessagePart $part[, int $position = null ]) : mixed

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

Parameters
$part : IMessagePart

The part to add.

$position : int = null

Optional insertion position 0-based index.

Return values
mixed

addRawHeader()

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

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

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.

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).

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

Tags
see
IMessagePart::getContentStream()
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 = null ]) : string|null
Parameters
$default : string = null

Optional default value to return if not applicable/defined

Return values
string|null

the disposition.

getContentId()

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

public getContentId() : string|null
Return values
string|null

the content ID.

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.

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.

getSignaturePart()

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

public getSignaturePart() : IMimePart

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
IMimePart

getSignedMessageAsString()

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

public getSignedMessageAsString() : string

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

Tags
see
IMessage::setAsMultipartSigned

to make the message a multipart/signed message.

Return values
string

or 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

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.

Tags
see
IMessage::getSignedMessageAsString

to get a string with CRLFs normalized

Return values
StreamInterface

or 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.

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.

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 $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

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).

removeAttachmentPart()

Removes the attachment at the given index.

public removeAttachmentPart(int $index) : mixed

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
mixed

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).

save()

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

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

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 : string|resource|StreamInterface

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
mixed

saveContent()

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

public saveContent(string|resource|StreamInterface $filenameResourceOrStream) : mixed

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 : string|resource|StreamInterface

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) : mixed

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

IMessage::getSignedMessageAsString
Return values
mixed

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 ]) : mixed

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.

public setContent(string|resource|StreamInterface $resource[, string $resourceCharset = MailMimeParser::DEFAULT_CHARSET ]) : mixed
Parameters
$resource : string|resource|StreamInterface

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(string|resource|StreamInterface $resource[, mixed $charset = 'UTF-8' ]) : mixed

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 : string|resource|StreamInterface

UTF-8 encoded content.

$charset : mixed = 'UTF-8'

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 $value, int $offset) : mixed
$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

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.

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(string|resource|StreamInterface $resource[, string $contentTypeCharset = 'UTF-8' ]) : mixed

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 : string|resource|StreamInterface

UTF-8 encoded content.

$contentTypeCharset : string = 'UTF-8'

the charset to use as the text/plain part's content-type header charset value.
