How can the array_push() function be used to add elements to an existing PHP session array?

To add elements to an existing PHP session array, you can use the array_push() function to append new elements to the end of the array. This function takes the session array as the first parameter and the element(s) to be added as subsequent parameters. By using array_push() within the PHP session, you can easily update the array with new values without losing the existing data. 

session_start();

// Initialize the session array if it doesn't exist
if (!isset($_SESSION['myArray'])) {
    $_SESSION['myArray'] = array();
}

// Add elements to the session array using array_push()
array_push($_SESSION['myArray'], "New Element 1", "New Element 2", "New Element 3");

// Print the updated session array
print_r($_SESSION['myArray']);
