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
// 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：" . $last_fruit . "
";
// Output the remaining array
echo "剩余的数组是：
";
print_r($fruits);
?>

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
剩余的数组是：
Array
(
[0] => apple
[1] => banana
[2] => orange
)

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