Fake PageRank Detection Script

Hey Guys!

I have stumbled across a PHP script that checks the validity of PageRank.

Here is the code:

<?php

//copyright 2007 -> AllStar -> http://onicdesigns.com
set_time_limit(0);
ob_start();

function getweb($website)
{
   if(!$ch = curl_init($website)) {
    echo "Could not connect to $website";
       return;
   }
   curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt ($ch, CURLOPT_HEADER, 0);
   $output = curl_exec($ch);
   curl_close ($ch);
   return $output;
}


function checkpagerank($url)
{ 
    $total = getweb('http://www.google.com/search?hl=en&q=info%3A'.urlencode($url)); 
    $match_expression = '/<span class\=a>(.*)\/<\/span><\/font>/i';
    preg_match($match_expression,$total,$matches); 
    return strip_tags($matches[1]);    
}


function sayln($str)
{
  echo $str."<br />";
  ob_flush();
  flush();
  return;
}

include_once('getpr.php');
$google = new google_pr(); 

 if(isset($_POST['submit']))
 { 
    sayln('Checking for valid pageranks :) Wee...');

    $domains = explode("\n", $_POST['domains']); 
    foreach($domains as $domain)
    {   
        $rurl = null;
        $domain = trim($domain);
        $rurl = checkpagerank($domain);
        if($rurl == $domain)
        {
            $pagerank   = trim($google->get_page_rank('http://'.$domain));
            if($pagerank  != 0)  
             {
               sayln($rurl.','.$pagerank);
             } 
        }
        elseif($rurl == '')
        {
            $pagerank   = trim($google->get_page_rank('http://'.$domain));
            if($pagerank  != 0)  
             {
               sayln('<a href="http://www.google.com/search?hl=en&q=info%3A'.urlencode($domain).'">'.$domain.'</a>,'.$pagerank.',not found');
             }     
        }
    }
 } 
 else 
 { 
?>
<div style="text-align: center">
    <form action="fakepagerank.php" method="post">
        <textarea name="domains" cols="100" rows="20"></textarea>
        <br /><input type="submit" name="submit" value="Check For Valid Pagerank!" style="font-size: 30pt;" />
        
    </form>
</div>
<?php } ?>

PHP:

What the problem here is that it doesn't check properly. For everything it says for everything "Not Found"

Please can you help me out?

Thanks

 

It is working for me.

Checking for valid pageranks Wee...
pizza.com,4,not found

 

Yeah, I test it and it is not working. No results.

And there is another free script to do this.
I use it on my site.
www.proxywhereabouts.com/pr.php

 

I don't think its ment to say "Not Found" for valid pagerank!

Is there something wrong with the regex?

 

check your checkpagerank() function.
error is there.It is not returning correct result.

 

Are you able to tell me where it is?

I tried re-arranging it but still I am getting confused!

 

I don t know why, but after the last pagerank update, alot of fake pagerank checker tools stop working properly

 

Hi,

Can Anyone give any example of fake PR.??

 

Here is a working Fake PR checker for domains:

<?php

$domain=$_GET['domain'];

if (isset($domain)) {

        $rurl = checkpagerank ($domain,false);
        $rurl = str_replace("www.","",$rurl);$rurl = str_replace("/","",$rurl);
        if ($rurl == "unknown") die ("unknown");
        if ($rurl==$domain) { echo "valid"; }
        else { echo "fake: $rurl"; }

}

function checkpagerank($domain,$proxy) {
    $page = getPage('http://www.google.com/search?hl=en&q=info%3A'.$domain,'http://www.google.com/','Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.8) Gecko/2009032609 Firefox/3.0.8',1,5,false);
    if (empty($page['ERR'])) { $result = $page['EXE']; } else { die('error connecting to site'); }
    $result = $page['EXE'];
    $re = "/<cite(.*)>(.*)<\/cite>/Uis";
    preg_match($re,$result,$matches);
    if (isset($matches[0])) { return strip_tags($matches[0]); }
    else { return "unknown"; }
}

function getPage($url, $referer, $agent, $header, $timeout, $proxy=false) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, $header);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    curl_setopt($ch, CURLOPT_REFERER, $referer);
    curl_setopt($ch, CURLOPT_USERAGENT, $agent);
     if ($proxy) curl_setopt($ch, CURLOPT_PROXY,$proxy);
    $result['EXE'] = curl_exec($ch);
    $result['INF'] = curl_getinfo($ch);
    $result['ERR'] = curl_error($ch);
    curl_close($ch);
    return $result;
}
?>

PHP:

You need to also keep in mind that google will throttle you quickly and start sending messages saying "too many requests from this IP", causing an incorrect result...
