将查询数据传递给方法的正确方法？

Question

我有一个用户类，我想知道什么是“最推荐”的方式来处理插入？

选项1：使用现有对象

// insert a new user and return the user id 
public function insert() { 
    $sql = "INSERT INTO users (username, password, email, avatar, subscribe, created, last_login, valid) VALUES 
           (?, ?, ?, ?, ?, ?, ?, ?)"; 
    $sth = $this->db->prepare($sql); 
    $sth->bindParam(1, $this->username, PDO::PARAM_STR); 
    $sth->bindParam(2, $this->password, PDO::PARAM_STR); 
    $sth->bindParam(3, $this->email, PDO::PARAM_STR); 
    $sth->bindParam(4, $this->avatar, PDO::PARAM_STR); 
    $sth->bindParam(5, $this->subscribe, PDO::PARAM_STR); 
    $sth->bindParam(6, $this->created, PDO::PARAM_STR); 
    $sth->bindParam(7, $this->last_login, PDO::PARAM_STR); 
    $sth->bindParam(8, $this->valid, PDO::PARAM_STR); 
    $sth->execute(); 

    return $this->db->lastInsertId(); 
} 

选项2：传递信息在作为数组

// insert a new user and return the user id 
public function insert(array $fields = array()) { 
    if(!empty($fields)) { 
     $sql = "INSERT INTO users (username, password, email, avatar, subscribe, created, last_login, valid) VALUES 
            (:username, :password, :email, :avatar, :subscribe, :created, :last_login, :valid)"; 
     $sth = $this->db->prepare($sql); 
     $sth->execute($fields); 

     return $this->db->lastInsertId(); 
    } 
} 

另一种选择？它有什么区别？

这两种方法都不错，但我个人认为第二个选项
