CodePudding user response：

You have confused the Webserver with the MySQL Server. Your web server is running on port 8080, not your MySQL Server. The MySQL server runs on port 3306 (by default) so your web application needs to connect to it on that port.

Change your mysqli connect string to:

$conn = new mysqli('localhost','root', '', 'votesystem', '3306');
