'WP Function to retrieve database connection

Is there a function or command that pulls the db connection info from the WP blog? I am writing a Plugin which would have to connect to the db to retrieve the info, wondering if there was one single command/function i could call which could connect. this would make the plugin portable and would work on any WP blog. is this possible?

See the Interfacing with the Database docs.

You should just be able to use the global (curse you, Wordpress) variable $wpdb in your plugin functions, ie:

global $wpdb;
//do stuff

Plugins also have a few methods for storing "options" in the database. I just found this article, it details things fairly well.

If you want to create your own query with database then you can try this

require_once('wp-config.php'); 
$con = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

You will get table prefix on $table_prefix this variable. I think it will help you. For preview you can check my github repo https://github.com/webdeveloperkanai/flutter-wordpress-blog-view-app-full-setup
