PHP login registration link database

First we create a conn.php file

The code is as follows:

    header("Content-type: text/html; charset=utf-8");//设置编码
    $con = mysql_connect("localhost","root","root") or die("数据库连接失败");
    mysql_select_db('login') or  die("指定的数据库不能打开");
    mysql_query("set names utf8");//设置数据库的字符集

First we set a character encoding. When there is Chinese in this file, there will be no garbled characters

Then connect to the database

localhost server root username root password

If your server is, then you can

$con = mysql_connect("","Username","Password") or die("Database connection failed");

Open your database, as shown in the fourth line above, database name for login
