how to make a scope variable global

[juworld]

Question!

i was wondering if there're anyways you can make a scope variable inside a function global?

One way would be via sessions.....

session_start();
function yada() {
$_SESSION['var']="Hey!";
}

echo "The variable is ".$_SESSION['var'];

//prints "Hey!"

I suppose another would be to return the variable in question...
