Question

我正在使用codeigniter框架构建一个应用程序。我有四种类型的用户

管理员
教师
学生
家长

我为上面的用户创建了不同的控制器和相同的模型文件。此外，每个控制器文件至少150KB，我的应用程序加载速度低于预期。所以，如果我把控制器功能分成不同的文件和模型功能不同，那么我的应用程序将更快，现在？

Answer 1

我不确定哪个部分花费你的时间，但你在这个控制器功能中混合了很多动作所有数据库操作和读数都应该在模型中完成

此外，如果您想知道哪些事情会降低您的应用程序速度，Codeigniter会提供一个出色的基准测试和分析工具

如果您想查看摘要，您应该使用Profiler类 - 它将显示一些基准测试结果

将此行放在您的控制器中

$this->output->enable_profiler(TRUE);
