Question

我有问题，但是我不知道哪里出了错？

private function getUsersPasswordByEmail($email){

        $stmt = $this->con->prepare("SELECT 'password' FROM 'user' WHERE 'email' = ?");
        $stmt->bind_param("s", $email);
        $stmt->execute();
        $stmt->bind_result($password);
        $stmt->fetch();
        return $password;}

此行中有错误-

$stmt->bind_param("s", $email);

详细信息类型：错误消息：在布尔上调用成员函数bind_param（）文件：C：\ xampp \ htdocs \ MyApi \ includes \ DbOperations.php 行：63

尝试使用`反引号代替'单引号

$stmt = $this->con->prepare("SELECT `password` FROM `user` WHERE `email` = ?");
$stmt->bind_param("s", $email);

php中的此mysql查询有什么问题？
