require_once('DataObject.php'); $obj = new DataObject(); $obj->get_by_id('users', 1); // get user data from 'users' table where ID = 1
require_once('DB.php'); $options = array( 'dsn' => 'mysql:host=localhost;dbname=testdb', 'username' => 'testuser', 'password' => 'testpass' ); $db = DB::connect($options); $user = $db->get_by_id('users', 2);In this example, we create a new database connection using the PEAR DB package and then retrieve data from the 'users' table where ID = 2 using the `get_by_id` method. From the examples, it can be inferred that PHP DataObject is a package library that provides an object-oriented interface for managing database tables.
