複製代碼

問題描述;

       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.

最大的問題是LOG檔案占空間，沒多久就數十GB

答案

        這些是 PHP 的提示而非報錯，PHP 本身不需要事先宣告變數即可直接使用，但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.
