, string $encoded_data
[, int $flush_mode = ZLIB_SYNC_FLUSH
] )
Incrementally inflates encoded data in the specified context.
Limitation: header information from GZIP compressed data are not made available.

flush_mode
One of ZLIB_BLOCK,
ZLIB_NO_FLUSH,
ZLIB_PARTIAL_FLUSH,
ZLIB_SYNC_FLUSH (default),
ZLIB_FULL_FLUSH, ZLIB_FINISH.
Normally you will want to set ZLIB_NO_FLUSH to
maximize compression, and ZLIB_FINISH to terminate
with the last chunk of data. See the » zlib manual for a
detailed description of these constants.
Returns a chunk of uncompressed data, 或者在失败时返回 FALSE.
If invalid parameters are given, inflating the data requires a preset
dictionary, but none is specified, the compressed stream is corrupt or has an
invalid checksum, an error of level E_WARNING is
generated.
