(PHP 4 >= 4.3.0, PHP 5)stream_get_meta_data -- Retrieves header/meta data from streams/file pointers
blocked (bool) - TRUE if the stream is in blocking IO mode. See stream_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 Appendix J for more information about wrappers.
wrapper_data (mixed) - wrapper specific data attached to this stream. See Appendix J 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.
Note: 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.
Note: This function does NOT work on sockets created by the Socket extension.
The following items were added in PHP 5.0:
mode (string) - the mode (or permissions) of the URI associated with this stream.
seakable (bool) - whether the current stream can be seeked in.
uri (string) - the URI/filename associated with this stream.
