<span class="function"><a href="function.array-uintersect-assoc.html" class="function">array_uintersect_assoc()</a></span> gibt ein Array mit allen
Werten aus <code class="parameter">array1</code> zurück, die ebenfalls
in allen anderen Argumenten enthalten sind. Beachten Sie, dass anders
als in <span class="function"><a href="function.array-uintersect.html" class="function">array_uintersect()</a></span> die Schlüssel zum
Vergleich herangezogen werden.
Sowohl Daten als auch Indizes werden durch eine Callbackfunktion verglichen.

Für den Vergleich der Daten wird die angegebene Callbackfunktion
herangezogen. Diese muss einen Integer kleiner als, genau gleich oder
größer als Null zurückgeben, wenn das erste Argument entsprechend als
kleiner, gleich oder größer als das Zweite betrachtet wird.
