What is PHP Array Pop?

PHP Array Pop is a built-in function in PHP that allows you to remove the last element from an array and return it. This function is useful in various scenarios where you need to manage arrays dynamically.

Syntax of PHP Array Pop

The syntax of PHP Array Pop is straightforward and easy to understand. The function takes an array as an argument and returns the last element of that array after removing it. The syntax is as follows:

array_pop (array &$array) : mixed

The argument $array is the array that you want to remove the last element from. The function returns the value of the removed element.

Examples of PHP Array Pop

Let's now take a look at some practical examples of how you can use PHP Array Pop.

Example 1: Removing the Last Element from an Array

<?php

$fruits = array("apple", "banana", "cherry");
$last_fruit = array_pop($fruits);

print_r($fruits);
echo $last_fruit;

?>

In this example, we have an array of fruits, $fruits, and we use PHP Array Pop to remove the last element, "cherry", from the array. The function returns "cherry" as the value of the removed element and updates the $fruits array to exclude the last element.

Array ( [0] => apple [1] => banana )
cherry

Example 2: Using PHP Array Pop on an Empty Array

<?php

$empty_array = array();
$last_element = array_pop($empty_array);

if (empty($empty_array)) {
    echo "Array is empty";
}

if (is_null($last_element)) {
    echo "No element to pop";
}

?>

In this example, we have an empty array $empty_array and we use PHP Array Pop to remove the last element. The function returns NULL as the value of the removed element, which indicates that there was no element to pop.

Array is empty
No element to pop
