Hi, am trying to use/understand how a remote server works.

I have this insert.php which is on a mongoose server on my computer, and it is to insert data into mysql database which is on xampp also on my computer.

Is it possible to do such?

I read on tizag http://www.tizag.com/mysqlTutorial/mysqlconnection.php

MySQL localhost

If you've been around the internet a while, you'll know that IP addresses are used as identifiers for computers and web servers. In this example of a connection script, we assume that the MySQL service is running on the same machine as the script.

When the PHP script and MySQL are on the same machine, you can use localhost as the address you wish to connect to. localhost is a shortcut to just have the machine connect to itself. If your MySQL service is running at a separate location you will need to insert the IP address or URL in place of localhost. Please contact your web host for more details if localhost does not work.

in other words, am i to use in my mysqli connection page (on mongoose server), write "localhost,username,password" to refer to the mysql database, and it will be inserted?

please sorry am trying to put words to my idea if it does not seem correct but hope it makes sense.
