}
return $sign _name;


The above code runs the Times wrong:
Warning:call-time pass-by-reference have been deprecated in E:\PHPnow-1.5.6\htdocs\source\core\util\class.lunar.php on Line 2277 and 2274
2274 lines of code are list ($sign _start, $sign _name) = each ($signs [(integer) $month-1]);
2277 lines of code are list ($sign _start, $sign _name) = each (& $signs [$month-2 < 0? ($month = one): ($month-= 2)]);


}

IST ($sign _start, $sign _name) = each ($signs [$month-2 < 0? ($month = one): ($month-= 2)]);
