$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?
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 individuallybind*
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.
