[Script] Anti Spam assez éfficace, A consomer sans modération Options

[Him]

Bonjour
J'ai découvert il ya quelques mois un bout de code je ne sais plus ou sur la toile, qui se disait "bon" pour bloquer le spam de nos formulaires....

J'ai d'abbord "tester" le script en utilisant une nouvelle adresse e-mail sur ma boutique.
Fort est à croire que sur 3 mois je n'ai reçu que des demandes de client

(excepté 3 pseudos client africains qui malheureusement spam manuellement...)

alors voila, je vous fait profitez de ce script qui n'est pas difficile à mettre en place.

CODE

<?php

// First, make sure the form was posted from a browser.
// For basic web-forms, we don't care about anything
// other than requests from a browser:  
if(!isset($_SERVER['HTTP_USER_AGENT']))
{
  die ("Forbidden - You are not authorized to view this page");
  exit;
}

// Make sure the form was indeed POST'ed:
//  (requires your html form to use: action="post")
if(!$_SERVER['REQUEST_METHOD'] == "POST")
{
  die ("Forbidden - You are not authorized to view this page");
  exit;  
}

// Host names from where the form is authorized
// to be posted from:
$authHosts = array ("webserviteur.com");

// Where have we been posted from?
$fromArray = parse_url(strtolower($_SERVER['HTTP_REFERER']));

// Test to see if the $fromArray used www to get here.
$wwwUsed = strpos ($fromArray['host'], "www.");

// Make sure the form was posted from an approved host name.
if(!in_array(($wwwUsed === false ? $fromArray['host'] : substr(stristr($fromArray['host'], '.'), 1)), $authHosts))
{  
  //logBadRequest();
  header("HTTP/1.0 403 Forbidden");
   exit;  
}

// Attempt to defend against header injections:
$badStrings = array("Content-Type:",
     "Content-Type: text/plain;",
     "MIME-Version:",
     "Content-Transfer-Encoding:",
     "Content-Transfer-Encoding: 7Bit",
     "bcc:",
     "cc:");

// Loop through each POST'ed value and test if it contains
// one of the $badStrings:
foreach($_POST as $k => $v)
{
  foreach($badStrings as $v2)
  {
   if(strpos($v, $v2) !== false)
   {
    //logBadRequest();
    header("HTTP/1.0 403 Forbidden");
     exit;
   }
  }
}  

// Made it past spammer test, free up some memory
// and continue rest of script:  
unset($k, $v, $v2, $badStrings, $authHosts, $fromArray, $wwwUsed);

// Puis ici ta fonction mail avec tes traitements éventuels !
