GLOBALS OFF ReWriting Considerations

[halojoy]

I have downloaded a php script software.
Was designed in them 'old days' when register_globals = ON

Now I do never run anything with registering globals = ON
and I probably never will.

I have searched and replaced these variables in all files in this software
Like this:
$HTTP_xxxx_VARS with $_xxxx
Where xxxx = SERVER, POST, GET, FILES or COOKIE

This is one of several functions in this software that have updated:

function uploadImg($img) {
    global $_FILES;
    global $_SERVER;
...
// original was:
function uploadImg($img) {
    global $HTTP_FILES_VARS;
    global $HTTP_SERVER_VARS;
...

Now my question is,
Should I use these variables, as globals?
I do not want more than necessary variables to be global.

Can I remove 'global' in front of $_FILES, in such functions?
Will they stop working, if I do that?

Thanks.

all those predefined arrays $FILES $POST $GET etc are already global. They are accessable from any scope. It wont hurt at all to remove
global $FILES
global $_SERVER
from inside the function.
As it is now its pretty pointless to have them since they are global already.
