PHP运行出现Notice : Use of undefined constant 的解决办法

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
Copy after login

改为：

error_reporting = E_ALL & ~E_NOTICE
Copy after login

还有个不是办法的办法就是

在每个文件头上加

error_reporting(0);
Copy after login

虽然不好弄但是可以解决问题
