To fix this error you are receiving:要修复您收到的此错误：
Firstly, don't use mysql , it is deprecated, use mysqli .首先，不要使用mysql ，它已被弃用，请使用mysqli 。
Secondly, you have no specified database connection in your query command, how can PHP query a non-existent database?其次，你的查询命令中没有指定数据库连接，PHP如何查询一个不存在的数据库？
Your MySQL query is failing (thus not a valid MySQL resource), trying dying it and seeing the error, although the error is likely fixed by doing this:您的 MySQL 查询失败（因此不是有效的 MySQL 资源），尝试关闭它并查看错误，尽管通过执行以下操作可能修复了错误：
$dbc = mysqli_connect(HOST, USERNAME, PASSWORD, DBNAME); //The database connection
$regver = mysqli_query($dbc, "SELECT * FROM users WHERE u_name = '".$username."' OR u_email = '".$email."'");
If it doesn't work, die it and see the error:如果它不起作用，则将其杀死并查看错误：
$regver = mysqli_query("SELECT * FROM users WHERE u_name = '".$username."' OR u_email = '".$email."'")
or die (mysqli_error($dbc);
