Methods

addChild()

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

public addChild(MessagePart $part[, int $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

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
Parameters
$message : string
$psrLogLevel : string
$exception : Throwable|null = null
Return values
static

attachContentStream()

Attaches the stream or resource handle for the part's content. The stream is closed when another stream is attached, or the MimePart is destroyed.

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

the content

$streamCharset : string = MailMimeParser::DEFAULT_CHARSET

the charset of $stream

Tags
see
IMessagePart::setContent()

to pass a string as the content.

see
IMessagePart::getContentStream()

to get the content stream.

see
IMessagePart::detachContentStream()

to detach the content stream.

Return values
static

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>

getAllParts()

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

public getAllParts([callable $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

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

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

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
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

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.
Tags

see
IMessagePart::__toString()

to write the part to a string and return it.

see
IMessage::save()

to write the part to a file, resource handle or Psr7 stream.

Return values
resource

the resource handle containing the part.

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.

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
Return values
bool

isTextPart()

Returns true if the content of this part is plain text.

public isTextPart() : bool
Return values
bool

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.

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.

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+' ]) : 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 : 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)

Tags

IMessagePart::getResourceHandle()

to get a resource handle.

see
IMessagePart::__toString()

to get the part in a string.

see
IMessage::save()

to write the part to a file, resource handle or Psr7 stream.

Return values
static

saveContent()

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

public saveContent(string|resource|StreamInterface $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 : string|resource|StreamInterface

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.
