How can the PHP function array_pop() be effectively used to remove the last element from an array stored in a PHP session?

To remove the last element from an array stored in a PHP session, you can use the `array_pop()` function to remove the last element of the array. You need to retrieve the array from the session, use `array_pop()` to remove the last element, and then update the session variable with the modified array.

// Start the session
session_start();

// Retrieve the array from the session
$array = $_SESSION['my_array'];

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

// Update the session variable with the modified array
$_SESSION['my_array'] = $array;
