$context
, string $data
, int $flush_mode
= ZLIB_SYNC_FLUSH
) : string|false

.

,
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.
