php-pdoConnect to MariaDB using PHP PDO

Since MariaDB is fully compatible with Mysql, using it with PDO is the same as Mysql.

  $pdo = new PDO('mysql:host=localhost;dbname=test', 'user', 'pwd');
} catch ( PDOException $e ) {
  die($e->getMessage());
}ctrl + cgithub

`$pdo` PDO connection object	`new PDO` create new PDO connection
`PDOException $e` exception will be thrown if connection failed	`mysql:` connect to MariaDB using Mysql protocol
