推荐答案

，您需要在页面的较早位置指定与数据库的连接.您应该将该变量放入查询中.假设您创建了一个名为$ con的变量.然后您的代码应该像这样.

you need to specify the connection that you made to your database somewhere earlier in your page. you should put that variable in the query. Suppose you made a variable called $con. Then your code should be like this.

mysqli_query($con,"INSERT INTO `counter`.`hits` (`page_hits`) VALUES ('".$hits."')");
