    sweet..

    i hacked it further and put a form field in there so you can punch the url to be checked into the form.

    im only a newbie php whiz so any if any of the pros see anything that needs some attention, drop a line.

    look forward to see how this works for everyone.

    PHP Code:
    <?php

    if(isset($_GET['getpr'])){


    // Edit this to your website url:
    $myWebSite = ($_POST['url']);

    define('GMAG', 0xE6359A60);

    //unsigned shift right
    function zeroFill($a, $b)
    {
    $z = hexdec(80000000);
    if (
    $z & $a)
    {
    $a = ($a>>1);
    $a &= (~$z);
    $a |= 0x40000000;
    $a = ($a>>($b-1));
    }
    else
    {
    $a = ($a>>$b);
    }
    return
    $a;
    }


    function
    mix($a,$b,$c) {
    $a -= $b; $a -= $c; $a ^= (zeroFill($c,13));
    $b -= $c; $b -= $a; $b ^= ($a<<8);
    $c -= $a; $c -= $b; $c ^= (zeroFill($b,13));
    $a -= $b; $a -= $c; $a ^= (zeroFill($c,12));
    $b -= $c; $b -= $a; $b ^= ($a<<16);
    $c -= $a; $c -= $b; $c ^= (zeroFill($b,5));
    $a -= $b; $a -= $c; $a ^= (zeroFill($c,3));
    $b -= $c; $b -= $a; $b ^= ($a<<10);
    $c -= $a; $c -= $b; $c ^= (zeroFill($b,15));

    return array(
    $a,$b,$c);
    }

    function
    GCH($url, $length=null, $init=GMAG) {
    if(
    is_null($length)) {
    $length = sizeof($url);
    }
    $a = $b = 0x9E3779B9;
    $c = $init;
    $k = 0;
    $len = $length;
    while(
    $len >= 12) {
    $a += ($url[$k+0] +($url[$k+1]<<8) +($url[$k+2]<<16) +($url[$k+3]<<24));
    $b += ($url[$k+4] +($url[$k+5]<<8) +($url[$k+6]<<16) +($url[$k+7]<<24));
    $c += ($url[$k+8] +($url[$k+9]<<8) +($url[$k+10]<<16)+($url[$k+11]<<24));
    $mix = mix($a,$b,$c);
    $a = $mix[0]; $b = $mix[1]; $c = $mix[2];
    $k += 12;
    $len -= 12;
    }

    $c += $length;
    switch(
    $len) /* all the case statements fall through */
    {
    case
    11: $c+=($url[$k+10]<<24);

    }
    $mix = mix($a,$b,$c);
    /*-------------------------------------------- report the result */
