use php to get google page rank

admin — Tue, 01 Jun 2010 17:37:47 +0000

Since the google not give a API or interface to get the google page rank, we have to use google toolbar to get the PR. In order to use php to query toolbarqueries.google.com to the get PR, I did a search ,but most of the codes are too old and can’t use or not work well, at last i got following script works well.

use php to get google page rank

there is all the codes :


function StrToNum($Str, $Check, $Magic)
{
    $Int32Unit = 4294967296;  // 2^32
 
    $length = strlen($Str);
    for ($i = 0; $i < $length; $i++) {
        $Check *= $Magic;
        //If the float is beyond the boundaries of integer (usually +/- 2.15e+9 = 2^31),
        //  the result of converting to integer is undefined
        //  refer to http://www.php.net/manual/en/language.types.integer.php
        if ($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;
}
 
//--> for google pagerank
/*
* 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);
}
   //--> for google pagerank

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) ) {

                $CheckByte += 9;
            }
            $CheckByte >>= 1;
        }
    }
 
    return '7'.$CheckByte.$HashStr;
}
        //get google pagerank
