These steps explain roughly how to create a MySQL database on your host server online. Most hosting companies offer free MySQL databases with the account. They are very easy to create and use after you do it once or twice.

1.	Log in to your control panel at your web host(where your web site is hosted). If you do not know where your site is hosted or how to log in, find out!
2.	From within your control panel search for an icon or a link that says "MySQL" or "Databases" and click on it.
3.	If there is a screen that asks which type of database you'd like to create, choose MySQL.
4.	Choose "create new database" or "create database".
5.	Type in the naming/password details for the database you are creating(write them down) and press submit. This will create the database on your server within minutes.
6.	After you see that the database is created and ready for use(past setup phase), get your database connection data to use in your PHP scripts. If you cannot find your newly created database's connection data, contact your host provider directly via phone or email and simply ask them where to.
7.	Finally, this page (click me) shows you how to add your database connection data to a little PHP script and allow database communication through script possible.
