我正在尝试遵循youtube上有关如何通过数据库编辑和插入图片的教程，并且按照youtube视频进行操作，但仍然遇到此问题
这是我看到的错误：
Warning: mysqli::__construct(): The server requested authentication method unknown to the client [caching_sha2_password] in C:\xampp\htdocs\exercise1\dbConfig.php on line 9
Warning: mysqli::__construct(): (HY000/2054): The server requested authentication method unknown to the client in C:\xampp\htdocs\exercise1\dbConfig.php on line 9Unable to connect database: The server requested authentication method unknown to the client
这是我的代码形式dbconfig：
//DB details
$dbHost = 'localhost';
$dbUsername = 'root';
$dbPassword = '';
$dbName = 'users';
//Create connection and select DB
$db = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName);
if($db->connect_error){
die("Unable to connect database: " . $db->connect_error);
}
