Dwa elementy tablicy uwa¿ane s± za identyczne wtedy i tylko wtedy je¶li
|
|
<literal>(string) $element1 === (string) $element2</literal>. S³ownie:
|

kiedy reprezentacje elementów w postaci stringów s± identyczne.

Zauwa¿, ¿e funkcja ta sprawdza tylko jest wymiar n-wymiarowej tablicy.

Oczywi¶cie mo¿na sprawdziæ g³êbsze wymiary wywo³uj±c
