Simply set EG(exception) = class... and experiment with the return value i don't know if it can be NULL or if it must be a valid string in case of an exception gets thrown. >> However with that last change the thing would be ok from my point of view. >> Perhaps you could also add an interface for that function as sterling once >> suggested.

Are there CD> any interfaces registered inside ZE2? I cound't find any... an interface is a normal class but one which has only abstract methods and no properties. So you can do the same as if you'd register an abstract class. But when you're done you change the class flag to also contain ZEND_ACC_INTERFACE.
