<p>Mit eregi() kann man in einer Zeichenkette (Zeichenkette) nach &Uuml;bereinstimmungen<br>
suchen, die durch den regul&auml;ren Ausdruck in Suchmuster angegeben
wurden.<br>
Wurde der Parameter regs angegeben, werden alle Treffer in einem Array<br>
gespeichert. Eine Kopie der urspr&uuml;nglichen Zeichenkette wird immer
in regs[0]<br>
gespeichert. Bei der Suche wird nicht zwischen Gro&szlig;- und Kleinschreibung<br>
unterschieden. Die Funktion gibt das Ergebnis true zur&uuml;ck, falls
sie das<br>
Suchmuster in der Zeichenkette findet, sonst false.<br>
