Re: [PHP-DEV] Bug #11527 Updated: session_unregister() seems not work properly From: Jani Taskinen (sniper <email protected>)
Date: 06/20/01

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.
Am I hallucinating?
