What happens for type conversion? Is the param cast to the hinted type?

The idea of type hinting for array and class is to make sure you get
something appropriate.

Rarely would you think of an array and cast it as an integer (or vice
versa), so it makes sense.

But with a string ("0"), an integer (0) or a boolean (false), they are
all the same, so does this mean we would be having to cast all the
params to the function/method?
