What are the potential pitfalls of adding values to an array in PHP without page refresh?

When adding values to an array in PHP without a page refresh, the potential pitfall is that the values may not persist between requests since PHP is a server-side language. To solve this issue, you can use sessions to store the array values across multiple requests. 

session_start();

if (!isset($_SESSION['my_array'])) {
    $_SESSION['my_array'] = [];
}

// Add value to the array
$_SESSION['my_array'][] = 'new value';

// Print the array values
print_r($_SESSION['my_array']);
