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
