If you check the php manual, you will see that it has been deprecated
如果您查看 php 手册，您会看到它已被弃用
How about you use the $_SESSIONvariable?
你怎么用这个$_SESSION变量？
$_SESSION["myusername"] = $username;
回答by MIIB
First you only select idfrom database, so there's no $row['active'].
Change $row['active']to $row[0]['id'].
首先你只select id来自数据库，所以没有$row['active']. 更改$row['active']为$row[0]['id']。
And do not use session_register("myusername");Use $_SESSION['myusername']=="something"
并且不要使用session_register("myusername");使用$_SESSION['myusername']=="something"
You could change your query to select id,username ...and then set $_SESSION['myusername']=$row[0]['username'];
您可以将查询更改为select id,username ...然后设置$_SESSION['myusername']=$row[0]['username'];
Ofcourse this method is not good, but for a beginner it should do it;
这种方法当然不好，但是对于初学者来说应该这样做；
