Create $var with some function

Hi there,

Someone know if can (if possible, how) i create a $var on my script like this:

function createvar($var) {
$var = 'foo';
global $var;
//or global $$var, i don't know it yet.
}

so i'd call,

createvar('myvar');

so i'd could call $myvar, like this:

echo $myvar; // prints 'foo'

is it possible?
