本文介绍了PHP PDO:获取样式FETCH_CLASS和FETCH_INTO获取到私有对象属性?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
相当短的问题,这里是一个例子:
Pretty short question, here is an example:
$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);
(从头开始,可能包含语法错误)
(written from top of the head, could contain syntax errors)
这两个是否直接提取到所述对象的 private 属性中?
我读它也绕过了 __ construct
函数,所以它会绕过私人状态吗?
Do those two directly fetch into the private properties of said objects?I read it also circumvents the __construct
function, so will it circumvent private status too?
推荐答案
很简单的答案:是的。
class Foo
{
private $id;
public function echoID()
{
echo $this->id;
}
}
$result = $statement->fetchAll(PDO::FETCH_CLASS, "Foo");
$result[0]->echoID(); // your ID
Aside:
Aside:
这将导致语法错误 $ statement-> fetchAll(PDO :: FETCH_INTO,$ User);
。您不能使用 fetchAll
方法使用 FETCH_INTO
。
This will cause syntax errors $statement->fetchAll(PDO::FETCH_INTO, $User);
. You can't use FETCH_INTO
with the fetchAll
method.
