Google Page Rank Check Using PHP

What is Google Pagerank?
It’s a ranking given by Google to any page (between 0 to 10) which is based on total numbers of backlinks to page. Pagerank is an algorithm to calculate the importance of webpage. In Search engine ranking, Pagerank is an important factor. Higher the pagerank will get higher SERP (search engine results page) position.

In this article, we explain how to get Google page rank for any website using simple PHP class.

index.php:

<?php

require_once 'GooglePageRank.php';

$webUrl=$_POST['website_url'];

$objGooglePageRank = new GooglePageRank();

$result =  "$webUrl has Google PageRank:". $objGooglePageRank->get_google_pagerank($webUrl);

?>

  GooglePageRank.php: (Class File)

<?php

class GooglePageRank{

public function get_google_pagerank($url) {

$query="http://toolbarqueries.google.com/tbr?client=navclient-auto&ch=".$this->CheckHash($this->HashURL($url)). "&features=Rank&q=info:".$url."&num=100&filter=0";

$data=file_get_contents($query);

$pos = strpos($data, "Rank_");

if($pos === false){} else{

$pagerank = substr($data, $pos + 9);

return $pagerank;

}

}

public function StrToNum($Str, $Check, $Magic){

$Int32Unit = 4294967296; // 2^32

$length = strlen($Str);

for ($i = 0; $i < $length; $i++) {

$Check *= $Magic;

if ($Check >= $Int32Unit) {

$Check = ($Check - $Int32Unit * (int) ($Check / $Int32Unit));

$Check = ($Check < -2147483648) ? ($Check + $Int32Unit) : $Check;

}

$Check += ord($Str{$i});

}

return $Check;

}

public function HashURL($String){

$Check1 = $this->StrToNum($String, 0x1505, 0x21);

$Check2 = $this->StrToNum($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);

}

public 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;

}

}

?>
