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

Thus, array_pop is a simple yet powerful tool for backend developers who need to manipulate array data efficiently.
