<function>array_shift</function> estrae il primo elemento di
<parameter>array</parameter> e lo restituisce, accorciando
<parameter>array</parameter> di un elemento e spostando tutti gli altri
all'indietro. Tutte le chiavi numeriche verranno modificate al fine di iniziare il conteggio da zero,
mentre gli indici alfabetici non verranno modificati. Se <parameter>array</parameter> &egrave; vuoto (o non &egrave; un array),
viene restituito &null;.
