}
}
}
abstract public boolean save () Creates/Updates a collection based on the values in the atributes abstract public static Phalcon\Mvc\Collection findById (string $id) Find a document by its id abstract public static array findFirst ([array $parameters]) Allows to query the first record that match the specified conditions <?php
