Getting A Collection
Getting a collection has the same syntax as getting a database:
<?php$connection = new MongoClient();$db = $connection->baz;// select a collection:$collection = $db->foobar;// or, directly selecting a database and collection:$collection = $connection->baz->foobar;?>
A collection is analogous to a table (if you are familiar with relational databases).
