Alsje.

In maanden weergeven moet je niet willen, want wat is een maand? 30 dagen? 31 dagen? vier weken? 365/12 dagen?

edit:
kan wel met deze functie: http://www.php.net/manual/en/datetime.diff.php

Ik snap de ballen van de functie,

Maar hij werkt nu goed dankzij ut script van Lennard

Laat me dit maar ook opslaan voor dat ik het ook nodig heb.
