今天修改公司的網(wǎng)站，提示Notice : Use of undefined constant ，通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:\Server\vhosts\www.lvtao.net\global.php on line 50

Notice: Undefined variable: content in E:\Server\vhosts\www.lvtao.net\libs\template.core.php on line 557

進入網(wǎng)站會出現(xiàn)大量類似下面的提示，但是可以正常顯示和運行

Notice: Use of undefined constant ctbTitle - assumed 'ctbTitle' in d:\ctb1.5\ctb\include\config.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量即可直接使用，但是對未聲明變量會有提示。一般作為正式的網(wǎng)站會把提示關掉的，甚至連錯誤信息也被關掉

關閉 PHP 提示的方法

搜索php.ini：

error_reporting = E_ALL

改為：

error_reporting = E_ALL & ~E_NOTICE

還有個不是辦法的辦法就是

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
