进入网站会出现大量类似下面的提示，但是可以正常显示和运行

notice: use of undefined constant ctbtitle - assumed 'ctbtitle' in d:\ctb1.5\ctb\include\config.php on line 23...

b答案：这些是 php 的提示而非报错，php 本身不需要事先声明变量即可直接使用，但是对未声明变量会有提示。一般作为正式的网站会把提示关掉的，甚至连错误信息也被关掉

关闭 php 提示的方法

搜索php.ini：

error_reporting = e_all

改为：

error_reporting = e_all & ~e_notice

还有个不是办法的办法就是

在每个文件头上加

error_reporting(0); 虽然不好弄但是可以解决问题！！！！！！这个比较好用
