Part of the concept comes from ZEND1 which segfaulted in such cases. Use google to find problems with using default_properties and ZEND1.

What read_property hook is used for? Return's property's zval? Do you mind if I contribute and add something to ZEND2 docs? "read_property - returns zval *, containing the value of the property. Is used when value of the property should be retrieved for reading. Keep in mind that ZEND2 engine doesn't use always your own defined read_property hook. Sometimes it uses only hash table returned by get_properties hook. So if your extension requires object's property to be readable with every internal function , you must implemement your own hooks that way , so they update object's properties hash table. In other words it is not guaranteed, that your read_property hook will be always used by ZEND2 engine." Piotras
