完整的链式封装已经完成,并且用在了我最近开发的小型框架——JunPHP中作为Model模型底层。这样就将其中最简单的一部分查询操作先开源给大家学习下
/*
链式操作一般有:
where 查询条件
field 指定查询结果集中的返回字段
order 排序
limit 限制查询结果
结尾方法:
select 执行查询返回二维数组
find 执行查询,只能返回一条数据,返回一维数组
*/
$db = new Model();
$res = $db->M('article')->order('id desc')->select();//返回查询结果的二维数组
$res = $db->M('article')->order('id asc')where('id=3')->find();//返回查询结果的一位数组,只能返回一条记录
