Remove the last element from an array in PHP

Learn, how to remove the last element from an array in PHP.

To remove the last element from an array, we can use the built-in array_pop() function in PHP.

Here is an example, that removes the last element popcorn from the following array

<?php
$food = array("salad", "cake", "cheese", "popcorn");
array_pop($food);
print_r($food);
?>

Output:

Array
(
    [0] => salad
    [1] => cake
    [2] => cheese
)

The array_pop() function modifies the original array.

If you want to preserve the original array and still remove the last element, then you can use the array_slice() function by passing 0 , -1 as a second and third arguments.

<?php
$food = array("salad", "cake", "cheese", "popcorn");
$removedlast = array_slice($food, 0, -1);
print_r($removedlast)
?>

Output:

Array
(
    [0] => salad
    [1] => cake
    [2] => cheese
)

The array_slice() function creates the new array instead of modifying the original array.
