How can PHP developers ensure that their applications remain functional for users who have disabled JavaScript in their browsers?

PHP developers can ensure that their applications remain functional for users who have disabled JavaScript in their browsers by implementing server-side validation and rendering. This means that all form submissions and interactions should be validated and processed on the server side, and any dynamic content should be generated using PHP rather than relying on client-side JavaScript. 

<?php
// Server-side form validation and processing
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST["name"];
    // Validate and process form data here
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>PHP Application</title>
</head>
<body>
    <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
        <input type="text" name="name" placeholder="Enter your name">
        <button type="submit">Submit</button>
    </form>
</body>
</html>
