inflate_add — Incrementally inflate encoded data

说明

inflate_add ( resource $context , string $encoded_data [, int $flush_mode = ZLIB_SYNC_FLUSH ] ) : string

Incrementally inflates encoded data in the specified context.

Limitation: header information from GZIP compressed data are not made available.

参数

context: A context created with inflate_init().
encoded_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.

返回值

Returns a chunk of uncompressed data, 或者在失败时返回 FALSE.

错误／异常

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.
