Yes, this will work - with the correction I've made, 'cause I'm not sure, if
you can assign two variables to 'global'...
But you can see, that it is not good to use the 'global' keyword, because
you must know the name of the variable, you use.
Look:
$name_1 = "Jan";
$name_2 = "Fritz";
function print_name($name_arg)
{
echo $name_arg;
}
print_name($name_1);
print_name($name_2);
You see, how flexible it is...
