Re: Bug #11527 Updated: session_unregister() seems not work properly

Hi Jani, you're not hallucinating. This was being discussed just before the lists went south, IIRC Andrei said he would commit a change. There was some nontrivial stuff involved, I just don't remember what it was. But I thought it'd be fixed in 4.0.6; if you still get this behavior with RC4 it most probably will have to wait. :( At 18:24 6/20/2001, Jani Taskinen wrote the following: -------------------------------------------------------------- >I'm confused now. > >1. register_globals=On -> This doesn't work: $HTTP_SESSION_VARS="value" >2. register_globals=Off -> This doesn't work: $varname="value" > >what is this?
