更好的错误处理方式？(Better way of error handling?)

 错误处理的最佳方式是什么？ 这就是我想到的： 
 
class test {

    public static function Payment($orderid, $total) {
        if (empty($orderid) && empty($total)) {
            return array('status' => 'fail', 'error' => 'Missing Data');
        }
    }

}
 
 我听说过Try / Exceptions，但是如何将它应用到我的代码中？ 如果你能提供一个很棒的例子！ 

What are best way of error handling? This is what I came up with:
 
class test {

    public static function Payment($orderid, $total) {
        if (empty($orderid) && empty($total)) {
            return array('status' => 'fail', 'error' => 'Missing Data');
        }
    }

}
 
I heard about Try/Exceptions but how to fit that into my code? If you could provide example that would be great!
