This should not happen. Ideally all notices, warnings, and errors should be handled in your code. To avoid this:

  1. Always define variables before you use them.
  2. Remember to check that a file exists before including it.
  3. Always handle potential errors according to coding standards. I.e. Show a relevant error to the user, fail silently, or log events to a file on the server.

Note. The above is probably not a complete list.
