In PHP

Create a simple registration and login form for a user membership system.

Create a way for a user to register with your script requiring information such as username, password, date of birth, phone number, e-mail address and favorite type of food.

Next, create a login form to let a user login once they have registered. This form would use their username and password to login.

Once a user has logged in, direct them to a members only page which will display the data they have previously registered with (e.g. favorite food, date of birth, etc).

Remember to validate all data, prevent SQL injections, ensure all required information is submitted and that if a user is not logged in they do not gain access to the special members area.
