Pagerank problem

Hello friends,
I have a problem about learning PR of websites.

The code that i use give an error for couple of days like :
Warning: file(http://www.google.com/search?client...&features=Rank&q=info:http://www.google.com): failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden

full code is:

function getrank($url) { 
    $url = 'info:'.$url; 
    $ch = GoogleCH(strord($url)); 
    $file = "http://www.google.com/search?client=navclient-auto&ch=6$ch&features=Rank&q=$url";
    $data = file($file);
    $rankarray = explode (':', $data[2]); 
    $rank = $rankarray[2]; 

	return $rank;

PHP:

Are there anybody who know this problem.

Now i can not get a PR value.

Please help..

 

cant test it here, because i dont have the code for your googleCH() function.
but maybe it helps to fake the referer:
http://www.google.com/search?client=opera&rls=en&q=test&sourceid=opera&ie=utf-8&oe=utf-8
just replace "test" with your query and try again.

 

hi
thanks for your answer.But i always get PR 0 Value this time.
full php code is:

            $a &= (~$z);
            $a |= 0x40000000;
            $a = ($a>>($b-1));
