array_shift

(PHP4 )

array_shift -- Pop an element off the beginning of array

Description

mixed array_shift (array array)

array_shift() shifts the first value of the array off and returns it, shortening the array by one element and moving everything down.

Beispiel 1. array_shift() example


$args = array("-v", "-f");
$opt = array_shift($args);
This would result in $args having one element "-f" left, and $opt being "-v".

See also array_unshift(), array_push(), and array_pop().

Anmerkung: This function was added in 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];
