codeigniter多项目共享的时候，导致Exceptions.php引入php_error.php报错
环境：codeigniter2.0因为项目有前后台，所以在根目录下新建admin文件夹，复制index.php放到admin目录下。编辑admin/index.php
修改项目位置：
$system_path = '../system';
$application_folder = '../application/admin';
然后在application下新建admin文件夹，复制几个需要的文件夹到application/admin下
但是涉及到错误处理的时候，怎么会出现路径不对的情况。
Warning: CI_Exceptions::include(../application/admin/errors/error_php.php) : failed to open stream: No such file or directory in D:\Program Files\Apache\htdocs\furniture\system\core\Exceptions.php on line 182

这种情况该怎么处理，路径错了。
$system_path = '../system';
$application_folder = '../application/admin';
请使用绝对路径 Hex 发表于 2012-4-15 18:56 static/image/common/back.gif
$system_path = '../system';
$application_folder = '../application/admin';
老大，我现在是在windows上面开发，
使用
$system_path = dirname(__FILE__).'../system';
$application_folder = dirname(__FILE__).'../application/admin';
运行提示错误：Your system folder path does not appear to be set correctly. Please open the following file and correct this: index.php
是不是我哪里弄错了。
绝对路径是使用http://localhost/proname/system还是dirname(__FILE__).'../system'; core 发表于 2012-4-15 21:34 static/image/common/back.gif

何谓绝对路径？
这里指的路径是“文件系统路径”，即为类似 C:\abc\def 这样的路径。
所以绝对路径就应该类似 C:\abc\def 这样的路径。 其实只是没有将 errors 文件夹复制进 admin 下
