Re: superglobals inside of function declarations

Hi, In general you are only allowed to use scalars as default values. This won't change. I suggest you do something like: function refresh($location = NULL) { if ($location === NULL) {

       $location = $_SERVER['PHP_SELF'];

} } At 11:26 AM 10/30/2003 +0100, Filip de Waard wrote:

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.
