OK I found it. It's caused by 'zend_hash_find(Z_OBJPROP_P((zval*)' which "obviously" invokes get_properties. And it is placed in my read_property hook. Thank you *all* for your patience! It would be good to mention about get_properties usage in OBJECTS2_HOWTO. http://cvs.php.net/viewvc.cgi/ZendEngine2/OBJECTS2_HOWTO?revision=1.6&view=markup There's no single word about it there. get_properties - called when object's properties HashTable should be fetched for reading. Unlike ZEND1 engine, ZEND2 does not directly read object's properties table. But instead get_properties handler is invoked. The most common usage is: * debugging with functions like print_r or var_dump * looking for a property of an object If custom extension implements own hook, it's recommended to return object's properties with all values assigned to properties. ...something like that :) Piotras
