What are the advantages of using AJAX forms over traditional form submission for handling database changes in PHP?

Using AJAX forms for handling database changes in PHP offers several advantages over traditional form submission. AJAX allows for asynchronous communication with the server, meaning that the user does not have to wait for the entire page to reload after submitting the form. This results in a smoother and more responsive user experience. Additionally, AJAX forms can provide real-time feedback to the user without needing to refresh the page, making it easier to show validation errors or success messages. 

// Example AJAX form submission in PHP
if(isset($_POST['data'])) {
    // Process form data and update database
    $data = $_POST['data'];
    
    // Perform database operations
    
    // Return response to AJAX request
    echo json_encode(['message' => 'Data successfully saved']);
    exit;
}
