PDO: Database connection on remote website

问题

This is an example of the database connection I'm using with my PDO queries:

$dsn = "mysql:host=localhost;dbname=some_db;charset=utf8";
$opt = array(
 PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION,
 PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC
);

$pdo = new PDO($dsn,'Username','Password', $opt);

How would I modify it if my database is located on www.mysite.com and I want to access the database from a different website?

You need to open up port 3306 to accept connections.

$dsn = "mysql:host=mysite.com;dbname=some_db;charset=utf8";
$opt = array(
 PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION,
 PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC
);

$pdo = new PDO($dsn,'Username','Password', $opt);
