<blockquote class="note"><p><strong class="note">Hinweis</strong>:
<span class="simpara">
Wenn Sie <span class="function"><strong>array_push()</strong></span> verwenden, um ein Element an
ein Array anzuhängen, ist es besser <em>$array[] = </em> zu
benutzen, da dies den zusätzlichen Aufwand vermeidet, eine Funktion
aufzurufen
</span>

<blockquote class="note"><p><strong class="note">Hinweis</strong>:
<span class="simpara">
<span class="function"><strong>array_push()</strong></span> gibt eine Warung aus, wenn das erste
Argument kein Array ist. Dies unterscheidet sich vom Verhalten von
<em>$var[]</em>, welches ein neues Array erzeugt.
