[Php] Anti Proxy Pro

[Guest Mecanik]

In ziua de azi,foarte multi hackeri folosesc Proxy,adica un alt IP pentru a ascunde IP-ul real.

Sunt mai multe tipuri de Proxy,si inca nu am reusit sa detectez orice Proxy...

Dar totusi am realizat un script,din mai multe surse gasite pe Google,si am reusit cumva sa fac un sistem Anti Proxy destul de bun!

Codul se poate salva ca antiproxy.php,si se poate include in index.php prin include_once('antiproxy.php'); Atentie: Codul inca nu a fost optimizat pentru versiunile PHP 5.3.X Daca apare vreo eroare tip : Notice: Undefined index , inseamna ca aveti PHP 5.3.X. Solutia:

error_reporting(E_ALL);

ini_set('display_errors', '0');

[/code]

Se pune in [b]index.php[/b] (doar in cazul de mai sus!)

Sper sa va fie de folos!

[i]PS: Am sa optimizez codul pentru PHP 5.3.X dupa sarbatori.[/i]
