I was wondering what the general rule on using the global driective versus passing in a variable by reference, why you should or shouldn't, etc. e.g. function () {
    global $db;
     $res =& $db->query( "SQL");
} or function ( &$db ) {
    $res =& $db->query( "SQL");
}

or function foo () {

    $db = & $GLOBALS['database'];
    $res = & $db->query();

} or function foo () {

    $res = & $GLOBALS['database']->query();

} Just some more possibilities... cheers Jens
