Doctrine_Collection is a collection of records (see Doctrine_Record). As with records the collections can be deleted and saved using Doctrine_Collection::delete() and Doctrine_Collection::save() accordingly. When fetching data from database with either DQL API (see Doctrine_Query) or rawSql API (see Doctrine_RawSql) the methods return an instance of Doctrine_Collection by default. The following example shows how to initialize a new collection: <code type="php"> $conn = Doctrine_Manager::getInstance() ->openConnection(new PDO("dsn", "username", "pw")); // initalizing a new collection $users = new Doctrine_Collection($conn->getTable('User')); // alternative (propably easier) $users = new Doctrine_Collection('User'); // adding some data $coll[0]->name = 'Arnold'; $coll[1]->name = 'Somebody'; // finally save it! $coll->save(); </code>
