I think that depends on what I do with the variable. PHP doesn't know how I intend to use it, and if I know I want an int and I don't want to test for browserland garbage in my variable everytime the function is called, then an automatic type conversion to int for my function can make perfect sense. Yes, I could force the developer using my function to cast the parameter as an int, but I'm certain conversion in the engine without a userland cast is faster, and it makes it more convenient to the consumer of my function since they can still treat it like a classic function.
