<function>array_diff_key</function> zwraca wszystkie warto¶ci z
|

<parameter>tablica1</parameter>, które nie s± obecne w ¿adnym z
|

pozosta³ych argumentów. Asocjacje s± zachowywane. Ta funkcja jest podobna
|

do <function>array_diff</function>, z tym, ¿e do porównania u¿ywane s±
|
|
klucze tablicy zamiast ich warto¶ci.

Dwa klucze z par <emphasis>klucz => warto¶æ</emphasis> s± uznawane za

równe tylko je¶li <literal>(string) $klucz1 === (string) $klucz2

reprezentacje tekstowe musz± byæ takie same.

Funkcja ta sprawdza tylko jeden wymiar n-wymiarowej tablicy. Mo¿na

sprawdzaæ g³êbsze wymiary przez u¿ycie, na przyk³ad
