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

### Beschreibung

array stream_get_meta_data ( resource `$stream` )

Returns information about an existing `stream` .

### Parameter-Liste

`stream`

  The stream can be any stream created by fopen(), fsockopen() and pfsockopen().

### Rückgabewerte

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.

  > Hinweis: 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 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.

- 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.

### Changelog

--- | ---
5.0.0 | The following entries were added in the returned array: mode, seekable, and uri.
4.3.0 | The following entries were added in the returned array: stream_type, wrapper_type, wrapper_data, and filters.
4.3.0 | socket_get_status() is an alias for this function. Prior to PHP 4.3.0, it was used to retrieve the first four items, for socket based streams only.
