Master PHP’s array_pop: Remove and Retrieve the Last Array Element

In PHP we often need to manipulate array data, and the built-in array_pop function provides a convenient way to pop the last element from an array.

The function’s syntax is: mixed array_pop ( array &$array ) It accepts an array by reference, removes the last element, and returns that element; if the array is empty it returns null.

Example:

<?php
// Define an array
$fruits = array("apple", "banana", "orange", "grape");

// Pop the last element
$last_fruit = array_pop($fruits);

// Output the popped element
echo "Popped element: " . $last_fruit . "
";

// Output the remaining array
echo "Remaining array:
";
print_r($fruits);
?>

The script defines an array of fruit names, uses array_pop to remove “grape”, assigns it to $last_fruit, and prints both the popped value and the remaining array.

Running the code produces:

Popped element: grape
Remaining array:
Array
(
    [0] => apple
    [1] => banana
    [2] => orange
)

Summary

By using PHP’s array_pop function you can easily remove and retrieve the last element of an array, making it a useful tool for handling array data.
