Allow me to be more precise. In version 4.1.0 of December 2001's change log, we find this entry: "Introduced $_GET, $_POST, $_COOKIE, $_SERVER and $_ENV variables, which deprecate the old $HTTP_*_VARS arrays. In addition to be much shorter to type - these variables are also available regardless of the scope, and there's no need to import them using the 'global' statement. (Andi & Zeev)" Therefore my prepetual confusion about which thingies are superglobals comes from the old $HTTP_*_VARS arrays, which are not superglobals, and their $_* vars which have the same data, but are superglobals, and the $GLOBALS variable, which has always been a superglobal. So when I was supposed to go convert all my $HTTP_*_VARS, I *also* had to get rid of all the places I used to have to make them global, but now I don't any more... Woof. Can't just global search and replace my source code, can I? Now I know why I'm making that change piece-meal. :-^ -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
