Whoa, session stuffage

Can anyone explain this...? session_start(); if (!isset($photo)) { # hits here first time only, then skips as it should $photo = new Photo; session_register("photo"); } #works $photo->m_Name = "something"; # works echo $photo->m_Name; # Undefined function! $photo->LoadSelfFromDatabaseByAdID($id); # Works $photo->Clear(); $photo = new class_photo; # Works! $photo->LoadSelfFromDatabaseByAdID($id); # Works $photo->Clear(); Why do the member variables work okay but the function calls are off? I've shut down the sessions fully via exiting the browser, and tried other methods which work. My calls are all the same, I've tried swapping the order of the includes, and the functions themselves in the file to see if it changes, but it follows that function. Is there a max namespace on session-registered methods off of a class? After all the PHP at night, I actually ENJOY going to work and back to my nice world of COM/DCOM and C++. *wink* Okay, maybe not the COM/DCOM part. =) -Szii
