<p>
Deze functie deelt de <em>string</em> in stukjes telkens een <em>regex</em> reguliere expressie wordt gevonden. Deze stukjes (substrings) worden in een apparte string of in een numerieke array bewaard dankzij de assignatie ( = ).<br/>
De array wordt telkens geherdimensioneerd tot alle substrings erin verwerkt kunnen worden
