　　Notice: Use of undefined constant ALL_PS - assumed ALL_PS in E:Servervhostswww.lvtao.netglobal.php on line 50

　　Notice: Undefined index: EaseTemplateVer in E:Servervhostswww.lvtao.netlibs emplate.core.php on line 51

　　Notice: Use of undefined constant uid - assumed uid in E:Servervhostswww.lvtao.netglobal.php on line 54

　　Notice: Undefined index: uid in E:Servervhostswww.lvtao.netglobal.php on line 54

　　Notice: Use of undefined constant cuid - assumed cuid in E:Servervhostswww.lvtao.netglobal.php on line 55

　　Notice: Undefined index: cuid in E:Servervhostswww.lvtao.netglobal.php on line 55

　　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...

　　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
