Member Function Documentation

◆ __toString()

Psr\Http\Message\StreamInterface::__toString ( )
inherited

Reads all data from the stream into a string, from the beginning to end.

This method MUST attempt to seek to the beginning of the stream before reading data and read the stream until the end is reached.

Warning: This could attempt to load a large amount of data into memory.

This method MUST NOT raise an exception in order to conform with PHP's string casting operations.

Return values
string

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ close()

Psr\Http\Message\StreamInterface::close ( )
inherited

◆ detach()

Psr\Http\Message\StreamInterface::detach ( )
inherited

Separates any underlying resources from the stream.

After the stream has been detached, the stream is in an unusable state.

Return values
resource|nullUnderlying PHP stream, if any

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ eof()

Psr\Http\Message\StreamInterface::eof ( )
inherited

◆ getContents()

Psr\Http\Message\StreamInterface::getContents ( )
inherited

Returns the remaining contents in a string.

Return values
string
Exceptions
RuntimeExceptionif unable to read or an error occurs while reading.

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ getMetadata()

Psr\Http\Message\StreamInterface::getMetadata ( $key = null)
inherited

Get stream metadata as an associative array or retrieve a specific key.

The keys returned are identical to the keys returned from PHP's stream_get_meta_data() function.

@externalurl http://php.net/manual/en/function.stream-get-meta-data.php

Parameters
string$keySpecific metadata to retrieve.
Return values
array|mixed|nullReturns an associative array if no key is provided. Returns a specific key value if a key is provided and the value is found, or null if the key is not found.

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ getSize()

Psr\Http\Message\StreamInterface::getSize ( )
inherited

Get the size of the stream if known.

Return values
int|nullReturns the size in bytes if known, or null if unknown.

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\CachingStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\LimitStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ isReadable()

Psr\Http\Message\StreamInterface::isReadable ( )
inherited

Returns whether or not the stream is readable.

Return values
bool

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ isSeekable()

Psr\Http\Message\StreamInterface::isSeekable ( )
inherited

◆ isWritable()

Psr\Http\Message\StreamInterface::isWritable ( )
inherited

◆ read()

Psr\Http\Message\StreamInterface::read ( $length)
inherited

Read data from the stream.

Parameters
int$lengthRead up to $length bytes from the object and return them. Fewer than $length bytes may be returned if underlying stream call returns fewer bytes.
Return values
stringReturns the data read from the stream, or an empty string if no bytes are available.
Exceptions
RuntimeExceptionif an error occurs.

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\CachingStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\LimitStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ rewind()

Psr\Http\Message\StreamInterface::rewind ( )
inherited

Seek to the beginning of the stream.

If the stream is not seekable, this method will raise an exception; otherwise, it will perform a seek(0).

See also
seek() @externalurl http://www.php.net/manual/en/function.fseek.php
Exceptions
RuntimeExceptionon failure.

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\CachingStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ seek()

Psr\Http\Message\StreamInterface::seek ( $offset,
$whence = SEEK_SET )
inherited

Seek to a position in the stream.

@externalurl http://www.php.net/manual/en/function.fseek.php

Parameters
int$offsetStream offset
int$whenceSpecifies how the cursor position will be calculated based on the seek offset. Valid values are identical to the built-in PHP $whence values for fseek(). SEEK_SET: Set position equal to offset bytes SEEK_CUR: Set position to current location plus offset SEEK_END: Set position to end-of-stream plus offset.
Exceptions
RuntimeExceptionon failure.

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\CachingStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\LimitStream, GuzzleHttp\Psr7\NoSeekStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ tell()

Psr\Http\Message\StreamInterface::tell ( )
inherited

Returns the current position of the file read/write pointer.

Return values
intPosition of the file pointer
Exceptions
RuntimeExceptionon error.

Implemented in GuzzleHttp\Psr7\AppendStream, GuzzleHttp\Psr7\BufferStream, GuzzleHttp\Psr7\FnStream, GuzzleHttp\Psr7\LimitStream, GuzzleHttp\Psr7\PumpStream, and GuzzleHttp\Psr7\Stream.

◆ write()
