You can create just one file you can change your DB.

Create database blog and create a connection table in PHP my admin

Here it's code and its data

Table structure for table `connction`

CREATE TABLE IF NOT EXISTS `connction` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `localhost` varchar(200) NOT NULL,
  `username` varchar(200) NOT NULL,
  `password` varchar(200) DEFAULT NULL,
  `db_name` varchar(200) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;

Dumping data for table `connction`

INSERT INTO `connction` (`id`, `localhost`, `username`, `password`, `db_name`) VALUES
(1, 'localhost', 'root', '', 'blog');

);
}
e
cho "Connected successfully";

$my_db = mysql_select_db("blog",$conn);

if (!$my_db) {
    die ('Can\'t use blog : ' . mysql_error());
}

 $my_sql_query = "select * from connction";

 $result =  mysql_query($my_sql_query);

 $row = mysql_fetch_array($result);

 echo "</br>";
 print_r($row);

/*
