I am having problems decompressing a zlib'd string located in a file.
In the file headers, the compression says that it is zlib.
But, when I 'gzinflate' the string, I get the error: gzinflate(): data error in <b
Is the below NOT a zlib or some strange variant ?
anyone know ?

// Convert the hex to a string
$string = pack("H*", $hex);
//echo it
echo "the compressed string is:". "\r\n";
echo $string;
//decompress the string
$uncompressed =gzinflate($string);
echo "the uncompressed string is: ".$uncompressed;
?>
The Output SHOULD look something like this:
