This what you was thinking about?

--- example 1 ---
$n='Hello1';

function g() {
$global $n;
echo $n;
}

g();
--- eof ---

--- example 2 ---
$n='Hello2';

function g() {
echo $GLOBALS['n'];
}

g();
--- eof ---

Both are IMHO not a good way to do, better to send a variable into the
function (you can use references too)

--- example 3 ---
$n='Hello';

function g(&$nn) {
$nn.='3';
}

g($n);
echo $n;

--- eof ---
