How can PHP and JavaScript work together to achieve the desired functionality of adding input fields on button click?

To achieve the functionality of adding input fields on button click, you can use JavaScript to dynamically create new input fields when the button is clicked. PHP can be used to process the form data once it is submitted. 

<?php
if($_SERVER['REQUEST_METHOD'] == 'POST'){
    // Process the form data here
    foreach($_POST['new_input'] as $input){
        // Handle each input field
    }
}
?>
