Is it a common practice to assume that many users have JavaScript disabled when developing PHP applications?

It is not a common practice to assume that many users have JavaScript disabled when developing PHP applications. Most modern websites rely heavily on JavaScript for dynamic functionality, so it is generally expected that users have JavaScript enabled in their browsers. However, it is always a good idea to provide a fallback option for users who have JavaScript disabled, such as server-side validation for form submissions. 

<?php
// Server-side validation for form submission
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $name = $_POST['name'];
    $email = $_POST['email'];

    if (empty($name) || empty($email)) {
        echo 'Please fill out all required fields.';
    } else {
        // Process form submission
    }
}
?>
