In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

<?php
// Simple DNSBL/RBL PHP function - trust me, it's better than checkdnsrr, fsock, socket_create, Net::DNSBL and Net::DNS
// Here's a [better] way to quickly check if an IP is in a DNSBL / RBL.  It works on Windows and Linux, 
//  assuming nslookup is installed.  It also supports timeout in seconds.

function ipInDnsBlacklist($ip, $server, $timeout=1) {
	$response = array();
	$host = implode(".", array_reverse(explode('.', $ip))).'.'.$server.'.';
	$cmd = sprintf('nslookup -type=A -timeout=%d %s 2>&1', $timeout, escapeshellarg($host));
	@exec($cmd, $response);
