Properties

$allChildrenParsed

protected bool $allChildrenParsed = false

true once all children of this part have been parsed.

$children

protected array<string|int, mixed> $children = []

Array of all parsed children.

$childrenStack

protected array<string|int, mixed> $childrenStack = []

Parsed children used as a 'first-in-first-out' stack as children are parsed.

$endBoundaryFound

protected bool $endBoundaryFound = false

set to true once the end boundary of the currently-parsed part is found.

$parentBoundaryFound

protected bool $parentBoundaryFound = false

set to true once a boundary belonging to this parent's part is found.

$messageHandle

private mixed $messageHandle = null

the raw message input stream handle constructed from $messageStream or null for a child part

$messageStream

private StreamInterface|null $messageStream = null

the raw message input stream for a message, or null for a child part.

$mimeBoundary

private string|null $mimeBoundary = null

NULL if the current part does not have a boundary, and otherwise contains the value of the boundary parameter of the content-type header if the part contains one.

$mimeBoundaryQueried

private bool $mimeBoundaryQueried = false

FALSE if not queried for in the content-type header of this part and set in $mimeBoundary.

$parent

private ParserPartProxy|null $parent = null

The parent ParserPartProxy if one is set, or null if part doesn't have a parent.

$streamContentEndPos

private int|null $streamContentEndPos = null

The offset read end position in the message's stream for the end of this part's content (body).

$streamContentStartPos

private int|null $streamContentStartPos = null

The offset read start position in the message's stream for the beginning of this part's content (body).

$streamPartEndPos

private int $streamPartEndPos

The offset read end position for this part. If the part is a multipart mime part, the end position is after all of this parts children.

$streamPartStartPos

private int $streamPartStartPos

The offset read start position for this part (beginning of headers) in the message's stream.

Methods

__destruct()

public __destruct() : mixed
Return values
mixed

getAddedChildAt()

Returns the added child at the provided index, useful for looking at previously parsed children.

public getAddedChildAt(int $index) : ParserPartProxy|null
Parameters
$index : int
Return values
ParserPartProxy|null

getLastLineEndingLength()

Returns the length of the last line ending read by MimeParser (e.g. 2 for '\r\n', or 1 for '\n').

public getLastLineEndingLength() : int

The line ending may not belong specifically to this part, so ParserMimePartProxy simply calls getLastLineEndingLength on its parent, which must eventually reach a ParserMessageProxy which actually keeps the length and returns it.

Return values
int

the length of the last line ending read

getMessageResourceHandle()

Returns the resource handle for a the message's stream, getting it from the parent part if this is a child part.

public getMessageResourceHandle() : resource

resource

getMessageResourceHandlePos()

Shortcut for calling ftell($partBuilder->getMessageResourceHandle()).

public getMessageResourceHandlePos() : int

Return values
StreamInterface

getStreamContentLength()

Returns the length of this part's content stream.

public getStreamContentLength() : int

This method does not perform checks on whether the start pos and end pos of this part's content have been set, and so could cause errors if called before being set and are still null.

isMime()

Returns true if this part, or any parent, have a Content-Type or MIME-Version header set.

public isMime() : bool
Return values
bool

true if it's a mime message or child of a mime message.

parseContent()

Requests the parser to parse this part's content, and call setStreamContentStartPos/EndPos to setup this part's boundaries within the main message's raw stream.

public parseContent() : static

The method first checks to see if the content has already been parsed, and is safe to call multiple times.

Return values
static

popNextChild()

Returns the next child part if one exists, popping it from the internal 'stack' of children, attempting to parse a new one if the stack is empty, and returning null if there are no more children.

public popNextChild() : IMessagePart|null
Return values
IMessagePart|null

the child part.

setEndBoundaryFound()

Returns true if the passed $line of read input matches this part's mime boundary, or any of its parent's mime boundaries for a multipart message.

public setEndBoundaryFound(string $line) : bool

If the passed $line is the ending boundary for the current part, $this->isEndBoundaryFound will return true after.

Parameters
