Note: This function will reset the array pointer of the input array after use.

Parameters

array

The input array.

Return Values

Returns the shifted value, or null if array is empty or is not an array.

Examples

Example #1 array_shift example

<?php
$stack = array("orange", "banana", "apple", "raspberry");
$fruit = array_shift($stack);
print_r($stack);
?>

The above example will output:

Array
(
    [0] => banana
    [1] => apple
    [2] => raspberry
)

and orange will be assigned to $fruit.
