Google Page rank checker script works on windows not on linux.

[simplyrahul]

ATTACHED THE WHOLE SCRIPT HERE

 

Hello,

 

I have tried developing a google page rank tool using this article.

 

http://www.devpapers.com/article/326

 

And it is working absolutely fine on my local machine using WAMP 5

However - when I am uploading this to my server inside a folder with CHMOD 755 and file pagerank.php CHMOD 644

It is not displaying the ranks. Does the fwite function needs the same file or displayed file to be 755 or something?

I added echo $out; after $out .= "Connection: Close\r\n\r\n" ;

And it displays on the page where i have included pagerank.php

 

So i realized that could not be the problem

 

Then i added this line $pagerank = substr($data, $pos + 9);

echo $pagerank;

 

And the pagerank is not being displayed

 

My localhost is windows XP but my server is running on linux.

 

Can anyone please help

 

 

I will paste the code here

 

pagerank.php

 

 

define('GOOGLE_MAGIC', 0xE6359A60);
class pageRank{
var $pr;
function zeroFill($a, $b){
$z = hexdec(80000000);
if ($z & $a){
$a = ($a>>1);
$a &= (~$z);
$a |= 0x40000000;
$a = ($a>>($b-1));
}else{
$a = ($a>>$b);
}
return $a;
}

function mix($a,$b,$c) {
$a -= $b; $a -= $c; $a ^= ($this->zeroFill($c,13));
$b -= $c; $b -= $a; $b ^= ($a<<;

Usage

 

Do following:

 

1. Save the code above as pagerank.php.

2. Download or create your own images to display each rank.

3. Create a directory "images" containing all page rank images.

4. See code below on how to use the class.

 

 

include("pagerank.php");
$gpr = new pageRank();
$gpr->printrank("http://www.yahoo.com");
//display image
echo $gpr->get_pr();
