Subject: superglobals inside of function declarations
From: dewaard@netcollective.nl (Filip de Waard)

Hello,

I've been using PHP for quite a while now and i'm getting interested
it's internal beheaviour. I'm wondering why it isn't possible to use a
global variable inside of a function declaration. For example:

<?
function refresh($location = $_SERVER['PHP_SELF'])
{
	//refresh and load $location
}
//refreshes the page
refresh();
//redirects to another page
refresh("http://www.php.net/");
?>

Of course there are ways to circumvent this problem that have the same
result, but require more code. IMHO allowing globals inside of function
declarions will create interesting possibilities that could result in
more efficient code.
