Destructor best practice?

There appear to be two different ways that I can free an internal structure when dealing with classes. The first is to declare a 'zend_objects_destroy_object' handler: ... retval.handle = zend_objects_store_put(intern, (zend_objects_store_dtor_t) zend_objects_destroy_object, my_free_function_callback, NULL TSRMLS_CC); retval.handlers = zend_get_std_object_handlers(); ... In which 'my_free_function_callback' is the callback that frees underlying structure information. The alternative is to use __destruct: PHP_METHOD(my_class, __destruct) { } ... static const zend_function_entry my_class_methods[] = { ... PHP_ME(my_class, __destruct, NULL, ZEND_ACC_PUBLIC | ZEND_ACC_DTOR) ... }; Which is considered best-practice? I'm leaning toward the latter, but want to make sure there aren't any issues with relying on the __destruct approach. -- Thomas Hruska CubicleSoft President I've got great, time saving software that you will find useful. http://cubiclesoft.com/
