是否可以在本地项目中使用在线数据库？

Question

Here is my database connection:

// connect to database and select database
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "spy";
$dbh_conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$dbh_conn->exec("set names utf8");
$dbh_conn->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$dbh_conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

It works fine since the database is exists in the local. Now I've uploaded the database on a server and I want to use that online database (instead of the local one) . Is it possible? If yes, what should I write as servername ?

Answer 1

All you need to do is set $servername to the host address of the remote server and provide the correct credentials. Provided the server is allowing connections, you should be able to connect to its database.
