PHP array_pop() Function: How To Remove Last Element From Array

In this tutorial, we will learn how to use the pop() function in PHP to delete the last element in a given array.

PHP array_pop() Function: How To Remove Last Element From Array

Array operations refer to the various manipulations that can be performed on arrays, such as accessing, modifying, adding, removing, sorting, and searching elements. Arrays are a fundamental data structure in computer programming and are used extensively in algorithms, data structures, and applications.

PHP pop() Function

The following depicts the syntax for the pop() function in PHP.

array_pop(array &$array): mixed

The function accepts only one parameter:

  1. array - the target array whose last element you wish to delete.

The function removes the last element in the array and return it to the caller.

NOTE: The function will reset() the array pointer of the input array after use.


Example pop() function usage.

// Create an array
$fruits = array("apple", "banana", "orange", "grape");

// Remove the last element from the array
$last_fruit = array_pop($fruits);

// Output the removed element and the updated array
echo "Removed element: " . $last_fruit . "<br>";

In this example, the array_pop() function is used to remove the last element "grape" from the $fruits array and store its value in the $last_fruit variable. The output would be:

Removed element: grape
    [0] => apple
    [1] => banana
    [2] => orange

As you can see, the $fruits array no longer contains the "grape" element, which has been removed by the array_pop() function.
