What are the potential pitfalls of using .htaccess to restrict access to files in PHP?

Using .htaccess to restrict access to files in PHP can be problematic because it relies on server configuration, which may not be available or allowed on all hosting environments. Additionally, .htaccess files can be easily overridden or ignored by server settings, potentially leading to security vulnerabilities. A more reliable and secure approach would be to use PHP code within the file itself to restrict access based on user authentication or permissions. 

<?php
session_start();

// Check if user is logged in
if(!isset($_SESSION['user_id'])) {
    header("HTTP/1.1 401 Unauthorized");
    exit;
}

// Allow access to the file
// Your file content here
