Initialize an incremental inflate context

inflate_init ( int $encoding [, array $options = array() ] ) : resource

Initialize an incremental inflate context with the specified encoding.

encoding

One of the ZLIB_ENCODING_* constants.

options

An associative array which may contain the following elements:

level: The compression level in range -1..9; defaults to -1.
memory: The compression memory level in range 1..9; defaults to 8.
window: The zlib window size (logarithmic) in range 8..15; defaults to 15.
strategy: One of ZLIB_FILTERED, ZLIB_HUFFMAN_ONLY, ZLIB_RLE, ZLIB_FIXED or ZLIB_DEFAULT_STRATEGY (the default).
dictionary: A string or an array of strings of the preset dictionary (default: no preset dictionary).

Returns an inflate context resource (zlib.inflate) on success, or FALSE on failure.

If an invalid encoding or option is passed to options, or the context couldn't be created, an error of level E_WARNING is generated.
