[Plasmacy]

Ich versuche ein zufälliges Labyrinth via PHP generieren zu lassen. In meinem Script scheint es erst einmal zu funktionieren, leider habe ich auch einen Logikfehler implementiert, den ich so nicht verstehe, sprich: Das Script läuft (noch) nicht so wie es laufen soll und ich komme nicht dahinter...
Weiss evtl. jemand von euch wo der Fehler steckt?

<?php
session_start();
if (!isset ($_SESSION["user_id"])) 
{ 
	header ("Location: index.php"); 
}
$user_id = $_SESSION['user_id'];
$user_level = $_SESSION['user_level']; 
?>

Kannst du denn mal kurz anreissen, wo das Problem liegt? Eine Onlinedemo wäre auch hilfreich, es möchte nicht jeder gleich seine Entwicklungsumgebung starten.

Hat sich zwischenzeitlich erledigt, das Script funktioniert inzwischen Einwandfrei
(Habe es mehrfach überarbeitet und einige Logikfehler entdeckt).
