add()

Adds data to the stream.

public add(mixed $data[, bool $reset = false ]) : mixed
Parameters
$data : mixed

Data to add to the stream. Can be a resource, Horde_Stream object, or a string(-ish) value.

$reset : bool = false

Reset stream pointer to initial position after adding?

Return values
mixed —

close()

Close the stream.

public close() : mixed
Tags
since
1.4.0
Return values
mixed —

end()

Move internal pointer to the end of the stream.

public end(int $offset) : bool
Parameters
$offset : int

Move this offset from the end.

Tags
since
1.4.0
Return values
bool —

True if successful.

eof()

Has the end of the stream been reached?

public eof() : bool
Tags
since
1.4.0
Return values
bool —

True if the end of the stream has been reached.

getChar()

Return a character from the string.

public getChar() : string
Tags
since
1.4.0
Return values
string —

Character (single byte, or UTF-8 character if $utf8_char is true).

getEOL()

Auto-determine the EOL string.

public getEOL() : string
Tags
since
1.3.0
Return values
string —

The EOL string, or null if no EOL found.

getString()

Returns the stream (or a portion of it) as a string. Position values are the byte position in the stream.

public getString([int $start = null ][, int $end = null ]) : string
Parameters
$start : int = null

The starting position. If positive, start from this position. If negative, starts this length back from the current position. If null, starts from the current position.

$end : int = null

The ending position relative to the beginning of the stream (if positive). If negative, end this length back from the end of the stream. If null, reads to the end of the stream.

Return values
string —

A string.

getToChar()

Get a string up to a certain character (or EOF).

public getToChar(string $end[, bool $all = true ]) : string
Parameters
$end : string

The character to stop reading at. As of 1.4.0, $char can be a multi-character UTF-8 string.

$all : bool = true

If true, strips all repetitions of $end from the end. If false, stops at the first instance of $end. (@since 1.5.0)

Return values
string —

The string up to $end (stream is positioned after the end character(s), all of which are stripped from the return data).

length()

Returns the length of the data. Does not change the stream position.

public length([bool $utf8 = false ]) : int
Parameters
$utf8 : bool = false

If true, determines the UTF-8 length of the stream (as of 1.4.0). If false, determines the byte length of the stream.

seek()

Move internal pointer.

public seek(int $offset[, bool $curr = true ][, bool $char = false ]) : bool
Parameters
$offset : int

The offset.

$curr : bool = true

If true, offset is from current position. If false, offset is from beginning of stream.
