Exit op regel 57 weg halen?

Nee die hoeft niet weg volgens mij. Maar heb je ook al in de daadwerkelijke file gekeken? Misschien dat het genereren ergens niet goed gegaan is?

Verder is dubbele quotes om de variabele $filename natuurlijk zeer overbodig:

Code (php)

<?php
readfile($filename)
?>

Is beter.
