global $HTTP_SESSION_VARS not global ???

Hi all, After a bit of testing, I've noticed, that the $HTTP_SESSION_VARS array isn't as global as the manual makes it. The following piece of code should produce 2 blank lines and a "click here" link the first time it's loaded. When you click on the link, I would expect two lines saying "something", but only the second one works. ----------------------------------------------------------- <?php session_start(); session_register("test"); $test = "something"; function foo() { print($HTTP_SESSION_VARS["test"] . "<br />\n"); } foo(); print($HTTP_SESSION_VARS["test"] . "<br />\n"); ?> <a href="<?=$PHP_SELF?>">Click here</a> ----------------------------------------------------------- I would expect the array $HTTP_SESSION_VARS to be global, and thereby available inside the foo() function. Have I misunderstood something in the manual? If you think of replying that I should use the "global" declaration please give a good argument why. I know it solves my problem, but it is still not right according to the manual ;) /watson
