Anti Flood script

Kod:

<?php


$cookie = $_COOKIE['yourcookie'];

$othercookie = $_COOKIE['yourothercookie'];


if($cookie && $othercookie > 0) $iptime = 20;  // Minimum number of seconds between visits for users with certain cookie

else $iptime = 10; // Minimum number of seconds between visits for everyone else

//echo("loaded ".$cookie.$iplogdir.$iplogfile.$ipfile.$newtime);

touch($iplogdir.$ipfile, $newtime); //this just updates the IP file access date or creates a new file if it doesn't exist in /iplog
?>

Bunu anti_dos.php adı ilə atırsınız saytınıza :(www yada public_html papkasina:)sonra iplog adında papka açırsan ve onunda içində iplog.dat adında fayl açıb chmod 666 verirsiniz
sonra index.php da

Kod:

include("anti_dos.php");

edirsiniz bu qədər
