Grabbing pagerank with Php?

I used to use a class to grab pagerank, but all it returns is a -1 now. It's the same pagerank.php class that everyone else was using. Does this still work or did something change or is it just a problem on my end somewhere?

 

yes
do you know
its get -1 in my in site
and recently
its cused in high load

 

good tips...but if anyone could tell more is better...!

 

Sounds like the code that google use may have changed, or something within your setup on your server does not work.

Might be an idea to show as the script or at least give more details on what part of the script has broken so we can have a decent attempt in helping you.

 

Heres how....

Usuage:

<?php
  include('pagerank.php');
  $pr = getPageRank('digitalpoint.com');
  echo 'Digitalpoint has PR '.$pr;
?>

PHP:

Now create or replace your exsisting file pagerank.php with this:

<?php
function StrToNum($Str, $Check, $Magic)
{
    $Int32Unit = 4294967296;
    $length = strlen($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;
}

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);
}

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) {
		$agents = array(
					'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30',

				);
	$useragent = @ini_get('user_agent');
	@ini_set('user_agent', $agents[array_rand($agents)]);
	$ch = CheckHash(HashURL($url));	
	$pr_url ="http://toolbarqueries.google.com/search?client=navclient-auto&ch=$ch&features=Rank&q=info:$url";		
	$data = file_get_contents($pr_url);
	@ini_set('user_agent', $useragent);	
	$pos = strpos($data, "Rank_");
	if($pos !== false)
	{
		$pr = trim(substr($data, $pos + 9));
		return str_replace("\n",'',$pr);
	}
	else
		return 0;
}
?>

Your Welcome to +Rep me

 

It has actually stopped working for me since a month or so and the PR seems to be inaccurate. Looks like google have blocked all toolbar queries using php.

 

hu?

They haven't blocked tool-bar queries, they've blocked how some are made, the code above works perfectly, try it.

 

This is perfect! Thanks! +REP

 

I used your PHP script and I got this error:
Fatal error: Cannot redeclare strtonum() (previously declared in /home/sites/weblinkcheck.com/public_html/pagerank.php:2) in /home/sites/weblinkcheck.com/public_html/pagerank.php on line 2

line 2:
function StrToNum($Str, $Check, $Magic){
...}

solved

 

Script works for me too, thanks a lot for it.

 

Super helpful, and just what I was looking for. Thanks for posting this!
