PHP array_pop

Summary: in this tutorial, you will learn how to use the PHP array_pop() function to remove an element from the end of an array.

Introduction to the PHP array_pop() function

The array_pop() function removes an element from the end of an array and returns that element.

Here’s the syntax of the array_pop() function:

array_pop ( array &$array ) : mixed

Code language: PHP (php)

In the syntax, the $array is the input array from which to return the last element.

If the input array is empty, the array_pop() function returns null.

Note that the array_pop() function modifies the input array.

The following example shows how to use the array_pop() function to remove the last element of an array:

<?php
$numbers = [1, 2, 3];
$last_number = array_pop($numbers);
echo $last_number; // 3

print_r($numbers);

Code language: HTML, XML (xml)

Output:

3
 Array
 (
 [0] => 1
 [1] => 2
 )

Code language: PHP (php)

How it works.

First, define an array that has three numbers 1, 2, and 3.
Second, remove the last element of the $numbers array and assign it to the $last_number variable. The $last_number is 3.
Third, show the $last_number and the elements of the $numbers array.
