When having to deal with parsing an IIS4 or IIS5 metabase dump I wrote a simple function for converting those MS hexidecimal values into their ascii counter parts. Hopefully someone will find use for it.

<?php
function hex_decode($string)  {
        for ($i=0; $i < strlen($string); $i)  {
        $decoded .= chr(hexdec(substr($string,$i,2)));
        $i = (float)($i)+2;
        }
return $decoded;
}
?>
