Now that I read what you really want :)
You can use a class to track a variable which may achieve what you
want like this:
class globalvariable {
var $gv = 0;
function globalvariable(&$var){
$this->gv =& $var;
}
}
$one = 1;
$g = new globalvariable($one);
echo 'global '.$g->gv.'<br>';
$one = 2;
echo 'global '.$g->gv.'<br>';
