// Include DataObject library and define connection parameters require_once('DataObject.php'); $dsn = 'mysql:host=localhost;dbname=my_database'; $user = 'root'; $password = 'password'; // Connect to the database $db = new PDO($dsn, $user, $password); $dataObject = new DataObject($db);In this example, we are connecting to a MySQL database located on localhost with the name `my_database`, using the username `root` and password `password`. The `DataObject` constructor takes a PDO object as its parameter and returns a new instance of the DataObject class. Other examples of using PHP DataObject include executing SQL queries, creating and deleting database tables, and retrieving data from databases. The package library for PHP DataObject is `PEAR::DB`.
