Description
mixed
array_pop ( array array)
array_pop() pops and returns the last value of
the array, shortening the
array by one element.
If array is empty (or is not an array),
NULL will be returned.

reset() the array pointer after
use.
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.

This function may
return Boolean FALSE, but may also return a non-Boolean value which
evaluates to FALSE, such as 0 or
"". Please read the section on Booleans for more
information. Use the ===
operator for testing the return value of this
function. |
