PHP Account system base

I created this project to serve as a basis for other projects that need an account system. It uses PHP and MySQL. This system contains the following features:

• Header and footer in a separate file
• Registering accounts
• Logging in and out
• Password reset via email
• Members-only pages
• Account editing

Usage

You can put the www folder on a publicly accessible website and import the users.sql file into your database. The credentials for mysql can be set in settings.php. You can also set the minimum session duration here.
cron/delete_expired_password_reset_tokens.php can be ran occasionally, for example every 24 hours, to clean up expired password reset tokens from the database.

If you want a page to members-only you can put the following code at the top of your PHP page:

include_once "includes/user.php";
$user = User::authUser();

For a full example page, you can look at index.php(Accessible without an account) or profile.php(Logged in accounts only)
