Not > both. Not true -- $HTTP_SESSION_VARS is *not* like $_SESSION, and its values are *not* auto-registered. In fact, I still have my copy of the 4.0.6 manual around, and it specifically gives this as an example: > Example 1. Registering a variable > > <?php > session_register("count"); > $HTTP_SESSION_VARS["count"]++; > ?> However, it's a little unclear on whether this should still work regardless of the register_globals setting, as it also gives this as an example: > Example 2. Registering a variable with register_globals enabled > > <?php > session_register("count"); > $count++; > ?> I guess I'd have to go away and try it to be sure of what behaviour occurs for each setting of register_globals -- but there seems little point given that using $_SESSION has been much the best option for several versions now!
