Global variable inside a constructor with PHP

Question

This should be obvious, but I\'m getting a bit confused about PHP variable scope.

I have a variable inside a Constructor, which I want to use later in a function in

Answer 1

Globals are considered harmful. If this is an outside dependency, pass it through the constructor and save it inside a property for later use. If you need this to be set only during the call to test, you might want to consider making it an argument to that method.
