Hello Bob, that's definitively wrong, actually there must be something wrong with your code. The '|' is to ensure that the parameter is optional. Thus if you moit the param it's return value is untouched which means you have to initaialize the returned zval * to null before passing its address to the parsing functions. The only way "unknown" gets send back is when you use an unhandled spec. But you are using "O" or did you actually missread and took zero? (which would be plain bullshit)
