使用核心ftp将网站上传到服务器后如何附加数据库？

Question

I uploaded complete website to server using Core FTP but i want to connect database and dashboard for website.

How to connect the database to website?

Please help me out....

I tried to connect using

$con = mysqli_connect('localhost', 'root', '', 'applicants');

OR

$con = mysqli_connect('IP Address or web URL', 'root', '', 'applicants');

Answer 1

The second option looks correct as 1st option doesn't have password in call.
DO as below example:

<?php
$con = mysqli_connect("localhost","my_user","my_password","my_db");

// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
?>

Here localhost is MySql server location
my_user is userId of MySql
my_password is Password of MySql
my_db is database name of MySql
