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); 
case 10: $c+=($url[$k+9]<<16); 
case 9 : $c+=($url[$k+8]<<8); 
/* the first byte of c is reserved for the length */ 
case 8 : $b+=($url[$k+7]<<24); 
case 7 : $b+=($url[$k+6]<<16); 
case 6 : $b+=($url[$k+5]<<8); 
case 5 : $b+=($url[$k+4]); 
case 4 : $a+=($url[$k+3]<<24); 
case 3 : $a+=($url[$k+2]<<16); 
case 2 : $a+=($url[$k+1]<<8); 
case 1 : $a+=($url[$k+0]); 
/* case 0: nothing left to add */ 
} 
$mix = mix($a,$b,$c); 
/*-------------------------------------------- report the result */ 
return $mix[2]; 
} 

//converts a string into an array of integers containing the numeric value of the char 
function strord($string) { 
for($i=0;$i<strlen($string);$i++) { 
$result[$i] = ord($string{$i}); 
} 
return $result; 
}

$pr = file("http://www.google.com/search?client=navclient-auto&ch=6$ch&ie=UTF-8&oe=UTF-8&features=Rank&q=$url"); 
$pr_str = implode("", $pr); 
return substr($pr_str,strrpos($pr_str, ":")+1); 
} 

echo "<br>The PR of ".$myWebSite." is: ".getPR($myWebSite);
