The function "header" does not work
<p>I have a problem with that header.
When the page is processed I will only exit();</p>

<pre><code>if($validate=='true') {
        $_SESSION['nome'] = $nome;
        $_SESSION['cognome'] = $cognome;
        $_SESSION['email'] = $email;
        $_SESSION['telefono'] = $telefono;
        $_SESSION['cellulare'] = $cellulare;
        $_SESSION['password'] = $password;
        $_SESSION['societa'] = $societa;
        $_SESSION['pi'] = $pi;
        $_SESSION['cf'] = $tax;
        $controllor = md5(uniqid(rand(), TRUE));

        ob_start();
             header("Location: index.php?nav=8&amp;controllor=".$controllor);
        ob_end_flush();
        exit();


    }
</code></pre>

<p>All variables above are filled correctly and $validate is equal to 'true'.</p>
