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？:'(

30 代码问题，也不排除是rpwt 你這個是什麽版本的CI? 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. * @accessprivate
5. * @param stringthe error severity
6. * @param stringthe error string
7. * @param stringthe error filepath
8. * @param stringthe error line number
9. * @returnstring
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 = $x.'/'.end($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 顶，期望高手来解决 已定义？ 咋回事:funk: 关注～～
