How can PHP interact with JavaScript to handle form data from dynamically added input fields?

When dynamically adding input fields to a form using JavaScript, the challenge is to ensure that PHP can still handle the form data submitted. One way to achieve this is by dynamically updating the form's structure in JavaScript to include the new input fields with unique names. These input fields can then be submitted to a PHP script using AJAX to process the form data. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    $dynamicInputs = $_POST['dynamicInputs'];
    
    // Handle the dynamically added input fields
    foreach ($dynamicInputs as $input) {
        // Process each input field here
        echo $input . "<br>";
    }
}
?>
