Using PHP's array_pop Function to Remove the Last Element from an Array

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

The function removes the final element from the given array and returns it, or returns null if the array is empty.

mixed array_pop ( array &$array )

Below is a practical example that defines an array of fruit names, uses 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：" . $last_fruit . "
";
// Output the remaining array
echo "剩余的数组是：
";
print_r($fruits);
?>

Running the 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 is a simple yet powerful tool for backend developers who need to manipulate array data efficiently.
