$_GET and register_globals off. How to recognize $_GET?

listenmirndt

Hi guys.

So with register_globals = On

You can pass URL variables to a page : IE
page.php?x=1&y=2&etc=etc

then you can use them like so :
echo $x; //prints : 1

But with register_globals = Off
echo $x; // is empty
echo $_GET[x] // prints : 1

So my question :

Is it possible to toggle register_globals on somhow? or somthing like this?

I have already written my script : without register_globals = Off taken into consideration. So instead of searching through all the code and changing $variable to $_GET[variable] Id like to just somhow just add a line of code to the top of each page that does this..

Can it be done?

Thanks

Yes in the php.ini.

Aside from editing PHP ini or .htaccess : is there an easier way to catch $GET variables without using $GET[variable] ?

Thanks

Yes it can be done using extract() but it's not recommended. What you do is check whether register globals is off or on and then extact the variables if necessary. Something like this but you'll want to read about extract in the php manual for more details. Use at your own risk!

if (!ini_get('register_globals') {
    extract($_GET, EXTR_SKIP);
}

Yeah... unless it's going to be absolutely impossible, I would honestly sit down and convert the code to use the superglobals rather than just imitating the register_globals directive.
