在 CodeIgniter 工作了几个月，在 Doctrine 工作了几个月。我最近使用https://github.com/wildlyinaccurate/CodeIgniter-2-with-Doctrine-2作为基础并使用generate_classes()函数（application/libraries/Doctrine.php，在构造函数结束前调用一次）从 mysql 表/列定义实体，在创建实体后评论它）：

编辑：如何将它用于相关表的CRUD 操作？我知道，阅读用户指南，但是（例如）如果$post = $entityManager->find("Customers", $idCustomer);是单行，哪个函数/语法返回所有行（和相关行）？
