Using PHP's array_pop Function to Remove and Return the Last Element of an Array

In PHP, handling array data often requires extracting the last element for further processing, and the built‑in array_pop function offers a convenient way to do this.

The array_pop function removes the final element from an array, returns that element, and returns null when the array is empty. Its syntax is:

mixed array_pop ( array &$array )

A practical example defines an array of fruit names, calls array_pop to pop the last fruit, and then prints both the popped value and the remaining array:

<?php // Define an array $fruits = array("apple", "banana", "orange", "grape"); // Pop and return the last element $last_fruit = array_pop($fruits); // Output the popped element echo "弹出的元素是：" . $last_fruit . "\n"; // Output the remaining array echo "剩余的数组是：\n"; print_r($fruits); ?>

Running this script produces the following output, showing that "grape" was removed and the array now contains only the first three fruits:

弹出的元素是：grape 剩余的数组是： Array ( [0] => apple [1] => banana [2] => orange )

Thus, array_pop provides a simple and effective method for retrieving and removing the last element of an array, which is especially useful in many backend data‑processing scenarios.
