title: Some ideas while planning php system
body: <p>I am just about to undertake building a relatively large PHP system, I just need some ideas on how to implement a certain feature. </p>
  
  <p>I will allow users to register. Once registered, the user will have a security level which will be assigned to their account. </p>
  
  <p>So if I had security levels 1, 2 and 3, what would be the best way to show certain things to people with certain security levels ? </p>
  
  <p>Thank you in advance. </p>
