How to work with register_globals off on PHP

Question

I use global variables on my website such GET,POST,FILES,SESSION . I wrote my website on a server where register_globals is on . And i just moved my website to another server where register_globals is off and i actually do not know how to deal with it.

For exmaple, i have this code:

$do = $_GET['do'];

or

$name = $_POST['name'];

How i understood, i can not do this, php can't extract this data. How can i change my code to receive data from GET,POST,SESSION,FILES?

Thank you

Answer 1

You misunderstand. $_GET & co are superglobals which are always available and cannot be disabled, your code will always work.

register_globals makes those $_GET values directly available as variables. Ie instead of $_GET['do'] you could use $do .

Answer 2

This is the proper way to access the vars and works with register_globals_gpc = off :

$do = $_GET['do'];

If register_globals_gpc = on the $_GET would automatically be extracted and this would work:

echo $do;

So if you are doing it the way you show then all is well. $_GET , $_POST , $_COOKIE , as well as $_SERVER and $_SESSION are already superglobal and available anywhere.

Answer 3

The quick and easy way would be using extract function.

extract($_POST);
extract($_GET);
extract($_COOKIES);

But this is VERY VERY VERY BAD from security and maintainablity aspect! You should rewrite the code, if possible, to:

$variable = $_POST['variable'];
..
