本文為大家講解的是PHP錯誤Notice : Use of undefined constant 的完美解決方法,這個php的非致命錯誤提醒在pph5.3以上的版本中出現的頻率非常好,主要是因為php.ini中的錯誤級別配置的問題,感興趣的同學參考下.
問題說明;
今天修改公司的網站，提示Notice : Use of undefined constant ，透過下面的方法解決了，最好是error_reporting(0);不需要更改配置
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.netlibstemplate.core: EaseTemplateVer in E:Servervhostswww.lvtao.netlibstemplate.core.php on Notm. - assumed 'uid' in E:Servervhostswww.lvtao.netglobal.php on line 54

Notice: Undefined variable: content in E:Servervhostswww.lvtao.netlibstemplate.core.php on line 557
進入網站會出現大量類似下面的提示，但是可以正常顯示和運行
Notice: Usena of untbund constant assumed 'ctbTitle' in d:ctb1.5ctbincludeconfig.php on line 23...
b答案：這些是PHP 的提示而非報錯，PHP 本身不需要事先聲明變數即可直接使用，但是對未宣告變數會有提示。一般作為正式的網站會把提示關掉的，甚至連錯誤訊息也被關掉
關閉PHP 提示的方法
搜尋php.ini：
error_reporting = E_ALL
改為：
error_reporting = E_ALL & ~E_NOTICE
還有個不是辦法的方法就是
在每個文件頭上加
error_reporting(0); 雖然不好弄但是可以解決問題！ ！ ！ ！ ！ ！這個比較好用
