stream_get_meta_data -- Retrieves header/meta data from streams/file pointers
Syntax
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 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 PHP's own internal buffer.
Note:
You shouldn't use this value in a script.
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 L for more information about wrappers.
wrapper_data (mixed) - wrapper specific
data attached to this stream. See Appendix L 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.
Documentation on filters can be found in the
Filters appendix.
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.
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.
