How can AJAX be utilized to improve user experience in PHP form submissions?

When submitting a form in PHP, the page typically reloads, causing a disruption in the user experience. By utilizing AJAX, we can submit the form asynchronously without reloading the page, providing a smoother and more seamless experience for the user. 

// PHP code snippet for handling form submission using AJAX

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    // Example: saving form data to database

    // Return a response
    $response = array("message" => "Form submitted successfully");
    echo json_encode($response);
    exit;
}
