使用准备好的语句更新记录，检查更新是否有效

问题描述：

我有一个查询来更新数据库中的记录，它工作正常，但我想知道如何检查更新是否已发生，以便我可以返回true并显示正确的消息?

I have a query that updates a record on my database, it works fine but i wanted to know how to check if the update has happened so i can return true and display the right message?

现在，我知道我可以执行SELECT查询:

Now i know with a SELECT query i can do:

if(stmt->fetch())

如果是这样，我将返回true并说找到记录"，但是我不知道如何针对更新查询执行此操作?

If that is true i return true and saying "records found" but i haven't got a clue how to do it for an update query?

有人知道怎么做吗?

$query = "UPDATE user
            SET password = ?
            WHERE email = ?";

if($stmt = $conn->prepare($query)) 
{
    $stmt->bind_param('ss', $pwd, $userEmail);
    $stmt->execute();

    //Check if update worked
}

感谢您的帮助.

检查以下内容是否有效

$query = "UPDATE user
        SET password = ?
        WHERE email = ?";

if($stmt = $conn->prepare($query)) 
{
$stmt->bind_param('ss', $pwd, $userEmail);
if ($stmt->execute()) 
{
// worked
} 
else 
{
// not worked
}

祝你好运！
