PHP警告错误处理办法
对于一个PHP新手，遇到错误是一件很恼火的事情。特别是当你写完一个页面去预览的时候，发现整个版面上面全是警告。

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
这是书写不规范导致的，如：$row[name], 正确写法为$row['name'];
