Looking through the source, there are a few extensions which create objects internally and when they do this (usually with an instanciate method), they typically set is_ref == 1. Like so:
object_init_ex(object, class_entry); object->refcount = 1; object->is_ref = 1; Why set the is_ref? Aren't objects treated as is_ref natively throughout the engine? Or is this just old code from PHP 4 days that is still hanging around? Thanks for the understanding. Bob Silva
