我有下面的代碼運行時我在HTML表單努力使代碼，將插入阿拉伯語數據導入mysql

按下一個按鈕，但我得到以下錯誤
Fatal error: Uncaught Error: Call to a member function set_charset() on null in C:\xampp\htdocs\Mortgage Project\db.php:21 Stack trace: #0 {main} thrown in C:\xampp\htdocs\Mortgage Project\db.php on line 21
我知道錯誤是關於set_char，但我是新的，並不真正瞭解這裏的問題，在此先感謝。
你真的想每次創建新表你運行你的腳本？ ô.o順便說一句。你錯過了'new mysqli'中的'db_name'作爲參考：http://php.net/manual/de/mysqli.construct.php – Twinfriends
** $ sql ** - > set_charset < - 在這裏看到一個問題？ –
@Twinfriends我希望數據庫只在不存在的情況下才能創建，因爲這個項目將被放入一個我根本無法控制的服務器中 –
