在不绑定的情况下使用 PDO

2021-12-26 00:00:00 php mysql pdo sanitization

$stmt = $conn->prepare('SELECT * FROM users WHERE user_id = :user_id');

$stmt->execute(array(':user_id' => $_GET['user_id']));

$result = $stmt->fetchAll(PDO::FETCH_OBJ);

我正在使用这样的 PDO，我需要清理 GET 参数吗?

I'm using PDO like that, do I need to sanitise GET parameter?

我知道如果我做 $stmt->bindParam(':user_id', $_GET['user_id'], PDO::PARAM_INT); 不是问题.但我的路安全吗?

I know if I do $stmt->bindParam(':user_id', $_GET['user_id'], PDO::PARAM_INT); than it is not a problem. But is my way safe?

推荐答案

是的，它很安全.execute 和 bind* 之间的唯一区别是:

Yes, it's safe. The only differences between execute and bind* are:

execute 一次接受多个参数，而您必须bind* 单独地bind*每个参数
bind* 允许您指定参数类型，而 execute 将所有内容绑定为字符串

execute accepts several parameters at once, while you have to bind* each one individually

bind* allows you to specify the parameter type, while execute binds everything as strings

将参数传递给execute 主要是一种方便的速记，它仍然是安全的.

Passing parameters to execute is mostly a convenience shorthand, it's still safe.
