function splitName($fullname){  
     $hyphenated = array('歐陽','太史','端木','上官','司馬','東方','獨孤','南宮','万俟','聞人','夏侯','諸葛','尉遲','公羊','赫連','澹臺','皇甫',

        $firstname = '';//前爲姓,後爲名  
        if($vLength > 2){  
            $preTwoWords = mb_substr($fullname, 0, 2, 'utf-8');//取命名的前兩個字,看是否在複姓庫中  
            if(in_array($preTwoWords, $hyphenated)){  
                $lastname = $preTwoWords;  
                $firstname = mb_substr($fullname, 2, 10, 'utf-8');  
            }else{  
                $lastname = mb_substr($fullname, 0, 1, 'utf-8');  
                $firstname = mb_substr($fullname, 1, 10, 'utf-8');  
            }  
        }else if($vLength == 2){//全名只有兩個字時,之前一個爲姓,後一下爲名  
            $lastname = mb_substr($fullname ,0, 1, 'utf-8');  
            $firstname = mb_substr($fullname, 1, 10, 'utf-8');  
        }else{  
            $lastname = $fullname;  
        }  
        return array($lastname, $firstname);  
}

其中，$hyphenated這個數組存的是複姓庫。
