PHP PDO:获取样式FETCH_CLASS和FETCH_INTO获取私有对象属性吗？

Question

很简短的问题,这是一个例子:

$prepared = $this->pdo->prepare("SELECT * FROM Users WHERE ID = :ID");
$statement = $prepared->execute(array(":ID" => $User_ID))
$result = $statement->fetchAll(PDO::FETCH_CLASS, "User");
//OR
$User = new User();
$result = $statement->fetch(PDO::FETCH_INTO, $User);

(从头顶写,可能包含语法错误)

那两个直接获取所述对象的私有属性吗？我读它也绕过了__construct函数,它也会绕过私有状态吗？

Answer 1

答案非常简短:是的.

class Foo
{
    private $id;
    public function echoID()
    {
        echo $this->id;
    }
}
$result = $statement->fetchAll(PDO::FETCH_CLASS, "Foo");
$result[0]->echoID(); // your ID

在旁边:

这将导致语法错误$statement->fetchAll(PDO::FETCH_INTO, $User);.您不能使用FETCH_INTO该fetchAll方法.
