php does have constants which are _always_ global.
define ("SCRIPT_NAME", $passed_in_script);
then you refer to it like
my_function() {
printf("script is %s",SCRIPT_NAME);
}
notice there are no quotes or '$' or anything.
i've recently changed $DEBUG to DEBUG for things like
define("DEBUG", 1);
my_db_function() {
$rid = $db->query($query);
if (!DB::isError) {
do_something_cool();
} else {
if (DEBUG) printf("<!-- bummer, query failed : %s
-->\n",$rid->getMessage())
}
