array_shift

(PHP4 )

array_shift --  Dépile un élément au début d'un tableau

Description

mixed array_shift (array array)

array_shift() extrait la première valeur d'un tableau et la retourne, en raccourcissant le tableau d'un élément, et en déplacant tous les éléments vers le bas.

Exemple 1. Exemple avec array_shift()


$args = array ("-v", "-f");
$opt = array_shift ($args);
Cet exemple aura pour résultat que $args ne contiendra plus que "-f", et $opt contient "-v".

Voir aussi array_unshift(), array_push(), et array_pop().

Note: Cette fonction a été ajoutée dans PHP 4.0.

I assume you mean php3.. I'd like to know how as well. Maybe something like:
<pre>
$value_from_beginning=$array[0];
for($i=0;$array[$i];$i++) {
$array[$i]=$array[$i+1];
}
unset( $array[$i] );
</pre>
hey, that seems to work! I just made that up on the spot 8)

But I don't think this will shorten the array, there will simply be a null element at the end. Sizeof() would still return the original number of elements in the array, right? Is there a way in 3.0 to resize an array?

Here's how according to bsilva@umesd.k12.or.us:

$temp = $arr["first_key"];
for (reset($arr), next($arr); $key=key($arr); next($arr)) {
$arr2[$key]=$arr[$key];
