'''gzencode — Create a gzip compressed string'''

=== Description ===
<code>
gzencode(string $data, int $level = -1, int $encoding = ZLIB_ENCODING_GZIP): string|false
</code>
This function returns a compressed version of the input data compatible with the output of the gzip program.

For more information on the GZIP file format, see the document: » GZIP file format specification version 4.3 (RFC 1952).

==== Parameters ====
'''data:'''
The data to encode.

'''level:'''
The level of compression. Can be given as 0 for no compression up to 9 for maximum compression. If not given, the default compression level will be the default compression level of the zlib library.

'''encoding:'''
The encoding mode. Can be `FORCE_GZIP` (the default) or `FORCE_DEFLATE`.

`FORCE_DEFLATE` generates RFC 1950 compliant output, consisting of a zlib header, the deflated data, and an Adler checksum.

==== Return Values ====
The encoded string, or false if an error occurred.

=== Examples ===
'''Example #1 Creating a gzip file'''
<pre>
$data = file_get_contents("bigfile.txt");
$gzdata = gzencode($data, 9);
file_put_contents("bigfile.txt.gz", $gzdata);
</pre>
