array_pop — Pop the element off the end of array

mixed array_pop ( array &$array )

array_pop() pops and returns the last value of the array, shortening the array by one element.

Returns the last value of array. If array is empty (or is not an array), NULL will be returned.

This function will produce an error of level E_WARNING when called on a non-array.

Example #1 array_pop() example


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

After this, $stack will have only 3 elements:

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

and raspberry will be assigned to $fruit.
