PHP: $_GET and $_POST in functions?

Question

I am flabbergasted by the code, where the GET-values, such as $_GET[\'username\'], are not included as parameters to functions.

When do you need to inc

Answer 1

You don't need to send them as function parameters as they are global variables (accessible everywhere in the code).

But it's always a good practice to filter and validate them before you use them in your code.
