<p>Mit similar_text() kann man die &Auml;hnlichkeit von zwei Strings (Zeichenketten)<br>
(first und second) berechnen.<br>
Wenn Sie im dritten Parameter eine Variable &uuml;bergeben, so wird similar_text()<br>
darin einen Prozentwert zur&uuml;ckgeben.<br>
Im unteren Beispiel wurde die Prozentausgabe zus&auml;tzlich mit sprintf()
formatiert.</p>
