[RESOLVED] PHP 6 global

prkarpi

Hi all. I looked for a solution on the web, but couldn't find it. Can someone tell me if this will still work in PHP 6:

function main() {
global $varone, $vartwo;
...php code
}
?>

I read that some global function are removed for the sake of security.
Thank you.

To the best of my knowledge, [man]global[/man] is not going away (and probably never will, since so much existing code depends on it). That being said, I would still try to get rid of it from your code, as it is generally frowned upon due to the way it tightly couples the function to the application and tends to hide the function's dependencies and side-effects.

You might be thinking of the currently deprecated register_globals option being removed for the sake of security.

Well, both of your answers suit me - thank you. I know PHP 5 needs $GET or $POST for the vars - I learned that from coming from PHP 4 and had to replace many pages of coding. But my question was about function() and declaring the vars with "global."

My question is this then for NogDog - what is the other way to declare vars within function() parameters - i.e. not using "global."

Thank you.

Pass them as arguments, possibly by reference if necessary.
