Methods
__toString()
Returns the message/part as a string, containing its headers, content and children.
public
__toString() : string
Convenience method for calling getContents() on IMessagePart::getStream().
Tags
Return values
string —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 —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.
Tags
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
Return values
static —detachContentStream()

public
detachContentStream() : static
Tags
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> —getAllHeaders()
Returns an array of all headers in this part.

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.
Tags
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.
Tags
Return values
array<string|int, IMessagePart> —An array of matching parts.
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.
Tags
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).
Tags
Return values
StreamInterface|null —the stream
getCharset()
Returns the charset of the content, or null if not applicable/defined.
public
getCharset() : string|null
Return values
string|null —the charset
getChild()

public
getChild(int $index[, callable $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

- $fnFilter : callable = null
-
Optional function accepting an IMessagePart and returning true if the part should be included.
Tags

getChildCount()
Returns the number of direct children under this part (optionally counting only filtered items if a callable filter is passed).
public
getChildCount([callable $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
-
Optional function accepting an IMessagePart and returning true if the part should be included.
Tags
Return values
int —The number of children, or number of children matching the the passed filtering callable.
getChildIterator()
Returns a \RecursiveIterator of child parts.
public
getChildIterator() : RecursiveIterator<string|int, IMessagePart>
The https://www.php.net/manual/en/class.recursiveiterator.php allows iterating over direct children, or using a https://www.php.net/manual/en/class.recursiveiteratoriterator.php to iterate over direct children, and all their children.
Tags
Return values

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

Parameters
- $fnFilter : callable = null
-
Optional function accepting an IMessagePart and returning true if the part should be included.
Tags
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
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.

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.

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.
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.
Tags
Return values
static —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 —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
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
Tags
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(string|resource|StreamInterface $resource[, string $resourceCharset = MailMimeParser::DEFAULT_CHARSET ]) : static
Parameters
- $resource : string|resource|StreamInterface
-
the content.
- $resourceCharset : string = MailMimeParser::DEFAULT_CHARSET
-
the charset of the passed $resource.

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.
