What are the limitations of using PHP for client-side real-time interactions in configurators?

PHP is a server-side language, meaning it cannot directly interact with the client in real-time. To enable real-time interactions in configurators, it is recommended to use a combination of PHP on the server-side and JavaScript on the client-side. JavaScript can handle real-time interactions and communicate with the server using AJAX requests to update the configurator dynamically.

// This is an example of how to use PHP to handle AJAX requests for real-time interactions in a configurator

// PHP code to handle AJAX request
if(isset($_POST['data'])){
    // Process the data received from the client
    $data = $_POST['data'];
    
    // Perform necessary calculations or database operations
    
    // Return the updated data back to the client
    echo json_encode($updatedData);
}
