replicate a mySQL database

[freejoey]

I host an online store, and I want to make a copy of the mySQL database so I can quickly make another similar online store.
Is there a way to replicate a mySQL database (I am currently using the phpMyAdmin software to manage the database)
Maybe if I could shell in to do this, would anyone know of the command I would use... ?
Thanx in advance for any suggestions!

phpMyAdmin has an option dump a database. Choose to dump it with the following options: structure and data, save as file.

Then just run the resulting .sql file on your new database.
