stream_get_meta_data

반환값

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 지원 프로토콜/래퍼 목록 for more information about wrappers.

• wrapper_data (mixed) - wrapper specific data attached to this stream. See 지원 프로토콜/래퍼 목록 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.
