What are some alternative methods to dynamically call functions based on user input in PHP?

When dynamically calling functions based on user input in PHP, one alternative method is to use a switch statement to map user input to specific functions. This allows for a more controlled and secure way of handling user input and executing corresponding functions. 

$user_input = $_GET['action'];

switch ($user_input) {
    case 'function1':
        function1();
        break;
    case 'function2':
        function2();
        break;
    default:
        echo 'Invalid action';
}

function function1() {
    // Function logic for function1
}

function function2() {
    // Function logic for function2
}
