$result = $collection->add('{"name": "Alfred", "age": 42, "job": "Butler"}')->execute();

// A unique _id is (by default, and recommended) generated by MySQL Server
// This retrieves the generated _id's; only one in this example, so $ids[0]
$ids        = $result->getGeneratedIds();
$alfreds_id = $ids[0];

// ...

print_r($alfreds_id);
print_r($collection->getOne($alfreds_id));
?>
