when the user logs in, put his username to the session. Eg.
//After logging in, add his name to the session. $_SESSION['user']=$username; Then in each page, check if $_SESSION is not null. If its null, then use header function to redirect the user back to the first page. If its not null, then continue with normal operations.

This wouldn't work since you are adding $_SESSION=$myusername; even without checking if hes a valid user. Secondly, $_SESSION will be null and not 0.
