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 beTRUE
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.
-
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 Supported Protocols and Wrappers for more information about wrappers.
-
wrapper_data (mixed) - wrapper specific data attached to this stream. See Supported Protocols and Wrappers for more information about wrappers and their wrapper data.
-
mode (string) - the type of access required for this stream (see Table 1 of the fopen() reference)
-
seekable (bool) - whether the current stream can be seeked.
-
uri (string) - the URI/filename associated with this stream.
This function does NOT work on sockets created by the Socket extension.
<?php $url = 'http://www.example.com/'; if (!$fp = fopen($url, 'r')) { trigger_error("Unable to open URL ($url)", E_USER_ERROR); } $meta = stream_get_meta_data($fp); print_r($meta); fclose($fp); ?>
The above example will output something similar to:
