stream_get_meta_data
Returns information about an existing stream.
Parameters
- stream
-
The stream can be any stream created by fopen, fsockopen pfsockopen and stream_socket_client.
Return Values
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.
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 for more information about wrappers.
wrapper_data (mixed) - wrapper specific data attached to this stream. See 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.
crypto (array) - the TLS connection metadata for this stream. (Note: Only provided when the resource's stream uses TLS.)
Notes
Note:
This function does NOT work on sockets created by the Socket extension.
