-- code end ??? i just read, that objects in php 5 automatically returned as reference? in my code it doesn't seems like that!! ps: variable m_objData contains a lot of data from a mysql db thanks for answers. As you can read in some of the posts here, it only SEEMS like the objects are passed by reference (it's a conspiracy!). I'm not sure if it'll help you, but try using the ampersand (&) symbol to force passing-by-reference.
