[HotelUnderSeige]

Well here it goes

<? session_start();  ?>
<?php
$rawr = rand(**** 10000);
$_SESSION['rawr'] = $rawr ;
$capcha = $rawr;
?>
<? echo("$rawr"); ?><form method="post" action="rawr.php">
capcha: <input type="text" size="10" maxlenght="5" name="rawr"> 
<input="sumbit">

<? session_start(); ?>
<?php
$capcha = $_POST['rawr'];

if ( $capcha == $rawr ) {
    echo "Thank you, you may proceed";
} else {
    echo "you /fail";
}
session_destroy();
?>

Rand = Random, it will randomize the numbers through the varibles ( 100-1000)
