php

i just start to practice with php built-in, gettype() and its return value. This function is capable to return testing result such as boolean, integer, unknown type, etc. But among those testing result, there's one caught my eyes : unknown type.

After reading gettype, and try to find some reference here, i can not get any. So, the question is what kind of type can be categorized as "unknown type" ? is it possible ? or am i just missing reading something ?
