<span class="function"><strong>array_unshift()</strong></span> fügt die übergebenen Elemente
am Anfang von <code class="parameter">array</code> ein. Beachten Sie,
dass die Liste von Elementen als Ganzes eingefügt wird, sodass
die eingefügten Elemente die selbe Reihenfolge haben. Die
numerischen Schlüssel werden so modifiziert, dass bei null zu
zählen begonnen wird, Strings als Schlüssel bleiben unverändert.

<p class="para">
Diese Funktion gibt die neue Anzahl der in
<code class="parameter">array</code> enthaltenen Elemente zurück.
