any ideas how to prevent this error?
$_SERVER is an array. and also a variable. we can be sure
it exists if we are running a webserver php module, so we don't need
to test if it's set or not BUT the index of the array pointed to
by 'SCRIPT_FILENAME' does not necessarily exist so
(the contents of the $_SERVER is different from server to server)...
$filename = basename(@$_SERVER['SCRIPT_FILENAME']);
if (!$filename) {
die('yuck!');
}
or something like:
if (!isset($_SERVER['SCRIPT_FILENAME'])) {
die('yuck!');
} else {
$filename = basename($_SERVER['SCRIPT_FILENAME']);
}
to see what's in $_SERVER do something like:
ecoh '<pre>'; // this line assumes you are viewing the output via a webbrowser!
print_r($_SERVER);
