Step 2 : Create Show Pagerank PHP File

pagerank.php

<?php
 
// Start Google Pagerank
 
 
 
// Important! This is pagerank check file path
 
include('pagerank-checker.php');
 
 
 
// Write your site that show pagerank
 
$pr = getPageRank('http://www.getrank.org');
 
 
 
// Show Page Rank
 
echo 'My Pagerank is '.$pr.'';
 
 
 
// End Google Pagerank
 
?> 

Code (markup):

 

No, actually not. Since Google has discontinued PageRank, this won't work at all. So no, the example is no longer good in any way, since it's completely, utterly useless.
