欲哭无泪啊！高手帮帮忙,我实在没辙了

我用codelgniter做了一个网站，上传到租用的虚拟空间上，平时没什么问题，但有时就会报下面这个错误，
实在想不出问题在哪里！只能请各位高人指点一下，是我代码的问题吗？还是服务器的问题？

代码问题，也不排除是rpwt

你這個是什麽版本的CI?

zh-snail

我用的是1.73版本的CI,
我不知道代码哪里写错了会出现这种问题，能不能写个错误的范例。
这个问题是偶然性发生，平常运行都没事，就不知道啥时突然就不行了！

交你怎么关系notice级别的错误：
使用CI的时候，如果一个变量没有值，CI就会提示 Undefined，用PHP的开发的人都知道，定义PHP的变量是不需要初始化任何的值，看这notice真烦人，决定关掉它，开始先搜 A PHP Error was encountered 只在error目录中找到error_php.php，不是想要的结果，这文件只是模板，再搜文件名：error_php，在 system/libraies中的Exceptions中发现

   1.     /**
   2.      * Native PHP error handler
   3.      *
   4.      * @access  private
   5.      * @param   string  the error severity
   6.      * @param   string  the error string
   7.      * @param   string  the error filepath
   8.      * @param   string  the error line number
   9.      * @return  string
  10.      */
  11.     function show_php_error($severity, $message, $filepath, $line)
  12.     {   
  13.         $severity = ( ! isset($this->levels[$severity])) ? $severity : $this->levels[$severity];
  14.     
  15.         $filepath = str_replace("\\", "/", $filepath);
  16.         
  17.         // For safety reasons we do not show the full file path
  18.         if (FALSE !== strpos($filepath, '/'))
  19.         {
  20.             $x = explode('/', $filepath);
  21.             $filepath = $x[count($x)-2].'/'.end($x);
  22.         }
  23.         
  24.         if (ob_get_level() > $this->ob_level + 1)
  25.         {
  26.             ob_end_flush();
  27.         }
  28.         ob_start();
  29.         include(APPPATH.'errors/error_php'.EXT);
  30.         $buffer = ob_get_contents();
  31.         ob_end_clean();
  32.         echo $buffer;
  33.     }

找到include(APPPATH.'errors/error_php'.EXT); 这行，把它注释掉，就OK了
