RE: [PHP] What does register_globals do?

"unless defined otherwise" was what I said. When I said that, I simply meant that you declare the variables as global within the function and/or class.

That's not quite right. Php's variable scoping is different than most langauges. Variables inside a function are always local, even with register_globals on (this has something to do with Rasmus' life experiences at IBM). So you would need to use global on a variable inside a function (unless it's passed in) and except for the 'magic' global arrays, $_POST, $_GET, $_COOKIE, $_SERVER, etc ------- register_globals on ---------- http://localhost/index.php?target=help <?php function echo_out() { global $target; echo "$target<br>"; } echo_out(); ?> ------- register_globals off ---------- http://localhost/index.php?target=help <?php function echo_out() { echo "{$_GET['target']}<br>"; } echo_out(); ?> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
