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. All numerical array keys will be modified to start counting from zero while literal keys won't be touched.

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

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

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

and orange will be assigned to $fruit.
