I was reading on the forum. Some people were getting flamed for asking about the register_globals function. They were getting scolded and told to have it OFF. PERIOD. Is it that bad? Unsafe?

$_GET, $_POST <<--- arre those going to be disabled in PHP6? What are other methods of transferring variables if those are going to get disabled.

I want to have my URL like this..

[a href=\"http://www.me.com/index.php?food=chicken&drink=beer\" target=\"_blank\"]http://www.me.com/index.php?food=chicken&drink=beer[/a]
[a href=\"http://www.me.com/index.php?food=fish&drink=gatorade\" target=\"_blank\"]http://www.me.com/index.php?food=fish&drink=gatorade[/a]
[a href=\"http://www.me.com/index.php?food=people&drink=blood\" target=\"_blank\"]http://www.me.com/index.php?food=people&drink=blood[/a]

ya know? does register globals have to be on? im hosting a game server website. would it lower the security? everyone says i'd get hacked? i dont understand.

Don't worry -- $_GET and $_POST will still work. When register_globals() is on, then for page.php?id=0, inside your code you can just say $id instead of $_GET['id']. That way, it declares all variables in the superglobals ($_ENV,$_GET,$_POST,$_REQUEST,$_SESSION). It's obvious why it's bad.

Given enough eyeballs all bugs are shallow. My Website
