<?php

 
// Place flood protection code at the top of the script you want to protect.
  // You can write protection code into separate file and include it in every
  // page of your site.

  // Sample protection code starts here...

  // Include the class definition module.

 
require_once ( '../class.floodblocker.php' );

 
// In the following line write the full path to temporary directory in which
  // you want to store flood counters. It is good idea to create such folder
  // somewhere outside your documents directory, to make it unaccessable from Web.
  // Don't forget that the directory must have permissions to write files in it.
  // IMPORTANT!
  // All files in this folder (except those that start with dot, e.g.'.htaccess')
  // will be deleted by FloodBlocker, so don't keep anything there.

 
$flb = new FloodBlocker ( 'tmp-ips/' );

 
// Create as many rules as you want...

 
$flb->rules = array (
   
10=>10, // rule 1 - maximum 10 requests in 10 secs
   
60=>30, // rule 2 - maximum 30 requests in 60 secs
   
300=>50, // rule 3 - maximum 50 requests in 300 secs
   
3600=>200 // rule 4 - maximum 200 requests in 3600 secs
 
);

 
// At last call CheckFlood(), it will return FALSE if flood detected on any
  // of specified rules.

 
if ( ! $flb->CheckFlood ( ) )
    die (
'Too many requests! Please try later.' );

 
// ... that's all. Enjoy!
