Is it possible to prevent unauthorized access to JavaScript pages by hiding the link in PHP applications? If so, what are the best practices to achieve this?

To prevent unauthorized access to JavaScript pages in PHP applications, you can use server-side validation to check if the user is authorized before serving the JavaScript file. One way to achieve this is by using session variables to track user authentication status.

<?php
session_start();

// Check if user is authenticated
if (!isset($_SESSION['authenticated']) || $_SESSION['authenticated'] !== true) {
    header("HTTP/1.1 403 Forbidden");
    exit;
}

// Serve the JavaScript file
header("Content-type: text/javascript");
include 'path/to/your/javascript/file.js';
?>
