inflate_init
Initialize an incremental inflate context with the specified encoding.
Parameters
- 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).
Return Values
Returns an inflate context resource (zlib.inflate) on success, or false on failure.
Exceptions and Errors
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.
Notes
Caution:
Unlike gzinflate, incremental inflate contexts do not constrain the length of the decoded data, so provide no automatic protection against Zip bombs.
