What are the potential drawbacks of relying solely on JavaScript for form interactions, and how can PHP be used as a fallback solution?

Relying solely on JavaScript for form interactions can lead to accessibility issues for users who have JavaScript disabled or unsupported. To provide a fallback solution, PHP can be used to handle form submissions and processing on the server-side, ensuring that the form can still be submitted and processed even if JavaScript is disabled. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    // Perform validation and other processing
    
    // Redirect to a success page
    header("Location: success.php");
    exit();
}
?>
