"allow static get_rows callbacks, eg. 'app_ui::get_rows':

Browse Source 
- on php5.3+ they get directly called via a variable: $callback($query,$rows,$readonlys)
- on php < 5.3 we instancate the class, an call the method non-static: $obj->$method($query,$rows,$readonlys)
--> allows application code to be prepared for static callbacks
Note:
- we can not use call_user_func, as it does NOT support passing by reverence, which is required for $rows and $readonlys parameter
- static callbacks allow to NOT instanciate the class again for the callback (without current dirty methods like placing the object in $GLOBALS[$class])"
