Porównuje klucze z <parameter>array</parameter> z kluczami z
|
|
<parameter>arrays</parameter> i zwraca różnicę.
|
|
Ta funkcja jest podobna do <function>array_diff</function>, z wyjątkiem
|
|
faktu że porównywane są klucze zamiast wartości.

Dwa klucze z par <literal>klucz => wartość</literal> są uznawane

za identyczne tylko gdy

<literal>(string) $key1 === (string) $key2 </literal>. Innymi słowy

wykonywane jest ścisłe sprawdzenie typu, więc reprezentacja tekstowa

musi być identyczna.

Ta funkcja sprawdza tylko jeden wymiar tablicy wielowymiarowej.

Można oczywiście porównywać głębsze wymiary używając

<literal>array_diff_key($array1[0], $array2[0]);</literal>.
