stream_get_meta

Description

array stream_get_meta_data ( resource stream)

Returns information about an existing stream_ The stream can be any stream created by fopen(), fsockopen() and pfsockopen()_ The result array contains the following items:

timed_out (bool) _ TRUE if the stream timed out while waiting for data on the last call to fread() or fgets()_
blocked (bool) _ TRUE if the stream is in blocking IO mode_ See socket_set_blocking()_
eof (bool) _ TRUE if the stream has reached end_of_file_ Note that for socket streams this member can be TRUE even when unread_bytes is non_zero_ To determine if there is more data to be read, use feof() instead of reading this item_
unread_bytes (int) _ the number of bytes currently contained in the read buffer_

The following items were added in PHP 4_3:

stream_type (string) _ a label describing the underlying implementation of the stream_
wrapper_type (string) _ a label describing the protocol wrapper implementation layered over the stream_ See Apéndice I for more information about wrappers_
wrapper_data (mixed) _ wrapper specific data attached to this stream_ See Apéndice I for more information about wrappers and their wrapper data_
filters (array) _ and array containing the names of any filters that have been stacked onto this stream_ Filters are currently undocumented_

Nota: This function was introduced in PHP 4_3, but prior to this version, socket_get_status() could be used to retrieve the first four items, for socket based streams only_
In PHP 4_3 and later, socket_get_status() is an alias for this function_

Nota: This function does NOT work on sockets created by the Socket extension_
