NEE!!!

Zet de table zooi in een var, en return die var vervolgens:

Je wilt zo min mogelijk echoen in functies!

Je kan in een functie geloof ik maar 1x iets returnen, dus je moet eerst zoals Rik doet een variabele ($var) defineren ($var =wink die we daarna kunnen vullen met ($var .= h; $var .= oi; return $var; zal dan dus hoi als output geven!
