There's no need to test PHP's set_error_handler() function. You only care that your error handling class works. Leave testing the PHP interpreter to the PHP developers.
:) Treat your class like any other class: instantiate it and call its methods, passing parameters to test different conditions.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
