PHP array_pop() – Popping the Last Element from an Array

The array_pop() function in PHP removes and returns the last element of an array, decreasing the array's length by one.

If the supplied argument is not an array or the array is empty, the function returns NULL and may emit a warning.

Parameter: $array – the array from which the last element will be popped.

Return value: The value of the last element of the array, or NULL if the array is empty or not an array.

Example:

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

Output:

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