After trawling the web I found this code that enables the generation of page rank via php . Its works on 32bit and 64bit machines..

<?php

function StrToNum($Str, $Check, $Magic)
{
$Int32Unit = 4294967296; // 2^32

$length = strlen($Str);
for ($i = 0; $i < $length; $i++) {
$Check *= $Magic;
//If the float is beyond the boundaries of integer (usually +/- 2.15e+9 = 2^31),
// the result of converting to integer is undefined

if ($Check >= $Int32Unit) {
$Check = ($Check - $Int32Unit * (int) ($Check / $Int32Unit));
//if the check less than -2^31
$Check = ($Check < -2147483648)? ($Check + $Int32Unit) : $Check;
}
$Check += ord($Str{$i});
}
return $Check;
}

/*
* Genearate a hash for a url
*/
function HashURL($String)
{
$Check1 = StrToNum($String, 0x1505, 0x21);
$Check2 = StrToNum($String, 0, 0x1003F);

$Check1 >>= 2;
$Check1 = (($Check1 >> 4) & 0x3FFFFC0 ) ($Check1 & 0x3F);
$Check1 = (($Check1 >> 4) & 0x3FFC00 ) ($Check1 & 0x3FF);
$Check1 = (($Check1 >> 4) & 0x3C000 ) ($Check1 & 0x3FFF);

$T1 = (((($Check1 & 0x3C0) << 4) ($Check1 & 0x3C)) <<2 ) ($Check2 & 0xF0F );
$T2 = (((($Check1 & 0xFFFFC000) << 4) ($Check1 & 0x3C00)) << 0xA) ($Check2 & 0xF0F0000 );

return ($T1 $T2);
}

/*
* genearate a checksum for the hash string
*/
function CheckHash($Hashnum)
{
$CheckByte = 0;
$Flag = 0;

$HashStr = sprintf('%u', $Hashnum) ;
$length = strlen($HashStr);

for ($i = $length - 1; $i >= 0; $i --) {
$Re = $HashStr{$i};
if (1 === ($Flag % 2)) {
$Re += $Re;
$Re = (int)($Re / 10) + ($Re % 10);
}
$CheckByte += $Re;
$Flag ++;
}

$CheckByte %= 10;
if (0!== $CheckByte) {
$CheckByte = 10 - $CheckByte;
if (1 === ($Flag % 2) ) {
if (1 === ($CheckByte % 2)) {
$CheckByte += 9;
}
$CheckByte >>= 1;
}
}

return '7'.$CheckByte.$HashStr;
}

function getpagerank($url) {

$fp = fsockopen("toolbarqueries.google.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET /search?client=navclient-auto&ch=".CheckHash(HashURL($url))."&features=Rank&q=info:".$url."&num=100&filter=0 HTTP/1.1\r\n";
$out .= "Host: toolbarqueries.google.com\r\n";
$out .= "User-Agent: Mozilla/4.0 (compatible; GoogleToolbar 2.0.114-big; Windows XP 5.1)\r\n";
$out .= "Connection: Close\r\n\r\n";

fwrite($fp, $out);

//$pagerank = substr(fgets($fp, 128), 4);
//echo $pagerank;
while (!feof($fp)) {
$data = fgets($fp, 128);
$pos = strpos($data, "Rank_");
if($pos === false){} else{
$pagerank = substr($data, $pos + 9);
echo $pagerank;
}
}
fclose($fp);

}

}

//check page rank for http://www.example.com
getpagerank('example.com');

?>

um .... thanks I think ... how do I use it?

I am always interested in obscure code like this :)
