# stream_get_meta_data

(PHP 4 >= 4.3.0, PHP 5)

stream_get_meta_data — Retrieves header/meta data from streams/file pointers

### 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 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 4.3.0:

- `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 List of Supported Protocols/Wrappers for more information about wrappers.

- `wrapper_data` (mixed) - wrapper specific data attached to this stream. See List of Supported Protocols/Wrappers 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 4.3.0, but prior to this version, socket_get_status() could be used to retrieve the first four items, for socket based streams only.
> In PHP 4.3.0 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 5.0.0:

- `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.
