should basic data validation come before a function call or be performed within the function?
I would do the validation inside the function. This avoids repeating the validation everywhere the function is called. It also makes the function more self-contained. It expects a certain input and complains, or returns false, if it doesn't get it.
yes, and of course shouldnt every function check it parametres before proceeding?
