Purpose

The PHP code snippet you provided is the starting point for a user authentication system. It handles the following tasks:

• Starts a PHP session.
• Regenerates the session ID for enhanced security.
• Includes necessary configuration, functions, and authentication functions.
• Checks if the user is already logged in and redirects them to the home page if so.
• Determines the current page URL and checks if it's running locally.
• If not running locally, redirects the user to the home page.

Key Features

• Session Management PHP sessions are used to store user information, such as their ID and role.
• Authentication Function The is_logged_in_user() function checks if a user is logged in based on the presence of user-related session variables.
• Redirection The code redirects the user to the home page if they are already logged in or if they are not running the script locally.

Functionality

1. The script starts a session and regenerates the session ID.
2. It includes the necessary configuration, functions, and authentication functions.
3. It checks if the user is logged in using the is_logged_in_user() function.
4. If the user is logged in, they are redirected to the home page.
5. The script checks the current page URL and determines if it's running locally.
6. If the page is not running locally, the user is redirected to the home page.
7. Finally, the HTML content is displayed, including a logo and buttons for login and registration.

Additional Notes

• The code assumes that the user ID and role are stored in session variables named user_id and user_role, respectively.
• The home.php page should handle user authentication and provide access to the home content.
• The auth/register.php page should handle user registration.
• The library/standard_header.php file should include necessary HTML header elements.
• The library/footer.php file should include the website footer.
