Type

Methods

__construct()

__construct(callable  $callable) 

AsyncResponseStream constructor.

Parameters

callable $callable

__toString()

__toString() : string

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.

Returns

string

close()

close() : void

Closes the stream and any underlying resources.

detach()

detach() : resource|null

Separates any underlying resources from the stream.

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

Returns

resource|null —

Underlying PHP stream, if any

getSize()

getSize() : integer|null

Get the size of the stream if known.

Returns

integer|null —

Returns the size in bytes if known, or null if unknown.

tell()

tell() : integer

Returns the current position of the file read/write pointer

Throws

\RuntimeException

on error.

Returns

integer —

Position of the file pointer

eof()

eof() : boolean

Returns true if the stream is at the end of the stream.

Returns

boolean

isSeekable()

isSeekable() : boolean

Returns whether or not the stream is seekable.

Returns

boolean

seek()

seek(integer  $offset, integer  $whence = SEEK_SET) 

Seek to a position in the stream.

Parameters

integer $offset

Stream offset

integer $whence

Specifies 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.

Throws

\RuntimeException

on failure.

rewind()

rewind() 

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).

Throws

\RuntimeException

on failure.

isWritable()

isWritable() : boolean

Returns whether or not the stream is writable.

Returns

boolean

write()

write(string  $string) : integer

Write data to the stream.

Parameters

string $string

The string that is to be written.

Throws

\RuntimeException

on failure.

Returns

integer —

Returns the number of bytes written to the stream.

isReadable()

isReadable() : boolean

Returns whether or not the stream is readable.

Returns

boolean

read()

read(integer  $length) : string

Read data from the stream.

Parameters

integer $length

Read up to $length bytes from the object and return them. Fewer than $length bytes may be returned if underlying stream call returns fewer bytes.

Throws

\RuntimeException

if an error occurs.

Returns

string —

Returns the data read from the stream, or an empty string if no bytes are available.

getContents()

getContents() : string

Returns the remaining contents in a string

Throws

\RuntimeException

if unable to read or an error occurs while reading.

Returns

string

getMetadata()

getMetadata(string  $key = null) : array|mixed|null

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.

Parameters

string $key

Specific metadata to retrieve.

Returns

array|mixed|null —

Returns 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.
