我有下面的代码运行时我在HTML表单努力使代码，将插入阿拉伯语数据导入mysql

按下一个按钮，但我得到以下错误
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
我知道错误是关于set_char，但我是新的，并不真正了解这里的问题，在此先感谢。
你真的想每次创建新表你运行你的脚本？ ô.o顺便说一句。你错过了'new mysqli'中的'db_name'作为参考：http://php.net/manual/de/mysqli.construct.php – Twinfriends
** $ sql ** - > set_charset < - 在这里看到一个问题？ –
@Twinfriends我希望数据库只在不存在的情况下才能创建，因为这个项目将被放入一个我根本无法控制的服务器中 –
