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

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? I understand case 2 but the case 1 ??? Aren't the global arrays supposed to work ALWAYS? With register_globals=off, the unregister/unset works after the third example script of this bug report is reloaded, with register_globals=On it works as expected. All this with PHP 4.0.6RC4, btw.
