title: PHP saving data for logged in users
body: <p>I'm quite new to PHP and would appreciate a piece of advice on storing data. I managed to create a fully functioning log in script that takes a registered user to their "members area". </p>
  
  <p>Next, I would like the user to be able to create their own content and save it. That content would then be accessible through their members area.</p>
  
  <p>This would not be an issue for me if there was only one user, but how can I make this work for more different users?</p>
  
  <p>EDIT: I'm not asking for code or any deep insight, I'd just like to know a general way of dealing with this.</p>
