关于require的使用问题
我的一个test.php文件引用了A.php,b.php和c.php文件，这样test.php无法正常运行，也不提示错误（坑爹的说，为毛就是不提示错误呢），这时去掉b.php和c.php的引用，test.php可以正常运行，即：只有A.php的时候可以正确运行，当然路径肯定是正确，再继续加上b.php，又无法运行了，此时我又单独运行b.php,坑爹的竟然能正常运行。请问这是肿么啦？
------解决方案--------------------
有错却又不提示错误，是因为你没有打开错误显示功能
只有A.php的时候可以正确运行，再继续加上b.php，又无法运行了
可能的原因是 b.php 中重复声明了 a.php 中的函数或类
你没有给出代码，无法给出进一步的建议
------解决方案--------------------
可以试试 ?> 换成 我碰到过一次这样的情况
------解决方案--------------------
常量 IN_DESTOON 在 common.inc.php 中定义
但 test.php 中引用 common.inc.php 在 config.inc.php 之后
config.inc.php 中的 defined('IN_DESTOON') or exit('Access Denied'); 将因为常量 IN_DESTOON 未定义而导致程序终止
因为 common.inc.php 已引用了 config.inc.php，所以 test.php 中的 require 'config.inc.php'; 应删去
