What are the potential benefits of using AJAX in PHP for handling form submissions without page reload?

When handling form submissions in PHP without page reload, using AJAX can provide a smoother user experience by allowing the form to be submitted in the background without refreshing the entire page. This can improve the overall speed and responsiveness of the website, as only the necessary data is sent back and forth between the client and server. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here

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