我正在运行PHP7.3。运行以下代码时：

$conn = mysqli_connect($servername, $username, $hashed_password);

if(!$conn){
    die("Connection failed: " . mysqli_connect_error());
}

我得到的输出是：

Warning: mysqli_connect(): The server requested authentication method unknown to the client [caching_sha2_password] in C:\localhost\mysql.php on line x

Warning: mysqli_connect(): (HY000/2054): The server requested authentication method unknown to the client in C:\localhost\mysql.php on line x
Connection failed: The server requested authentication method unknown to the client.

修复？
