inflate_add — Incrementally inflate encoded data
inflate_add ( InflateContext $context , string $data [, int $flush_mode = ZLIB_SYNC_FLUSH ] ) : string|false
Incrementally inflates encoded data in the specified context
.
Limitation: header information from GZIP compressed data are not made available.
context
A context created with inflate_init().
data
A chunk of compressed data.
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, or false
on failure.
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.
