Binary-safe gz-file write

int gzwrite ( resource $zp , string $string [, int $length ] )

gzwrite() writes the contents of string to the given gz-file.

zp: The gz-file pointer. It must be valid, and must point to a file successfully opened by gzopen().
string: The string to write.
length: The number of uncompressed bytes to write. If supplied, writing will stop after length (uncompressed) bytes have been written or the end of string is reached, whichever comes first.

Note: Note that if the length argument is given, then the magic_quotes_runtime configuration option will be ignored and no slashes will be stripped from string.

Returns the number of (uncompressed) bytes written to the given gz-file stream.

<?php
$string = 'Some information to compress';
$gz = gzopen('somefile.gz','w9');
