How to remove the last element from an array in PHP

Use the PHP array_pop() function

You can use the PHP array_pop() function to remove an element or value from the end of an array. The array_pop() function also returns the last value of array. However, if the array is empty (or the variable is not an array), the returned value will be NULL.

Let's check out an example to understand how this function basically works:

<?php
$sports = array("Baseball", "Cricket", "Football", "Shooting");
 
// Deleting last array item
$removed = array_pop($sports);
print_r($sports);
echo "<br>";
var_dump($removed);
?>
