Simple php User Login Script

Feel free to use this script and modify it. Please leave the credits in. This login script is based on php session data and does not use cookies. It has the ability to let users register themselves. The user inputs there name, username, email, website and password. This data is then stored in a text file. The script also gives users the ability to change their information from their profile. Php sessions can be called on anywhere as long as the user doesn’t navigate away from your site. This means that you can include anything about the user anywhere on your site. You can also block certain users, or just people who haven’t registered, from certain web pages.
