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

In PHP, the array_pop function is a convenient built‑in utility for popping the last element off an array and returning it.

The function signature is: mixed array_pop ( array &$array ) If the array is empty, the function returns null. It modifies the original array by removing its final element.

Below is a full example that defines an array of fruit names, uses array_pop to extract the last fruit, and then prints both the popped value and the remaining array:

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

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

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

Thus, array_pop provides a simple way to handle the last element of an array, which is especially useful in backend data‑processing tasks.
