What are the advantages and disadvantages of using JavaScript versus HTML for handling form submissions in PHP?

When handling form submissions in PHP, using JavaScript can provide a more interactive and responsive user experience by validating form inputs before submitting the data to the server. However, relying solely on JavaScript for form validation can pose a security risk as it can be easily bypassed by users disabling JavaScript in their browsers. On the other hand, using HTML for form submissions may not provide real-time validation but ensures that the data is validated on the server side, making it more secure. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    // Server-side validation
    if (empty($name) || empty($email)) {
        echo "Please fill out all fields.";
    } else {
        // Process form data
        // Insert data into database, send email, etc.
    }
}
?>
