phalcon框架中如何实现脱离模型进行sql查询?比如,我有表A和表B,在models/下有A.php这个model类,而没有B的,现在在A中需要对表B进行一次SQL查询,在不创建B的model类的情况下如何拿到B的数据? PHP 框架 分享到: ------解决方案--------------------$ar = $obj->fetchAll($sql); 或 $r = $obj->fetchOne($sql); 其实 Phalcon 的类都是可以单独使用的,并不一定非要在框架中使用 比如$connection = new \Phalcon\Db\Adapter\Pdo\Mysql(array( "host" => "localhost", "username" => "root", "password" => "", "dbname" => "test" )); //print_r(get_class_methods($connection)); //从支持的方法上看,只不过是在PDO上扩展了一些功能 $connection->query('set names gbk'); $t = $connection->fetchAll('select * from `123`', 1); print_r($t);登录后复制Array ( [0] => Array ( [id] => 1 [姓名] => 张三 [型号] => A8-300 [工位] => A [数量] => 200 [时间] => 2013-06-05 08:46:00 ) [1] => Array ( [id] => 2 [姓名] => 李四 [型号] => A8-300 [工位] => B [数量] => 121
