PHP401 - session info request...

Hi. I'm playing around a bit with sessions and have the next problems/questions : * why do session variables need tobe declared as global ones and * why do i have to set globals_register = on in php.ini to make it work and * why doesn't $HTTP_STATE_VARS work, even when the online documentation clearly refers to it Wouldn't it be logical if session variables are normal localy declared? And for performance gain as the php.ini states, why can't we use those session info with globals_register = off by using $HTTP_STATE_VARS? Thx for reading... ps. I'm using NT4.SP6a/Apache1.3.12/PHP4.0.1.pl2 --------------test.php-------------------------------------------------- <? // global $test; $test = 3; session_start(); session_register("test"); echo(sprintf("<p><a href= \"test_2.php?%s\">click</a></p>", SID)); ?> --------------test.php-------------------------------------------------- -------------test_2.php------------------------------------------------ <? session_start(); // echo $HTTP_STATE_VARS["test"]; if ( session_is_registered("test") ) { echo ++$test; } else { echo "not registered..."; } echo(sprintf("<p><a href= \"test_2.php?%s\">click</a></p>", SID)); ?> -------------test_2.php------------------------------------------------
