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:ctb1.5ctbincludeconfig.php on line 23...

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 另外，还有一个更变态的方法，在每个文件头上加： error_reporting(0); 屏蔽任何的错误提示，不推荐使用。
