Question

CodeIgniter是否提供调试模式，例如，在访问无效网址时？

Ruby on Rails确实在给出错误的URL时显示调试消息，并且控制器无法使用路由映射解析它。如何在CodeIgniter中启用此类调试消息？

剖析器......

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

...仅影响单个班级，但不影响所有路线。因此，在没有实际调试器模式的情况下进行调试有点困难。： - ）

Answer 1

profiler 更多的是性能分析，而不是调试器。要走的路是 implementing very popular xDebug with CodeIgniter 。

Answer 2

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
