How to test, deploy and administer CI app

I'm close to finishing an early version of my web app, and would like to get it online.

I am, however, very confused as to what to do from here.

I'd like automated testing and deployment (I think). I'd also prefer as little server administration as possible.

The tools I use are GitHub and PhpStorm.

I'm willing to pay for the necessary services.

One of the nice things about CodeIgniter is you can usually just FTP it up to your server and it works.  You will most likely have to use your web host's control panel to create a database and update your database configuration.  And you might have to create/alter an .htaccess file.

This is one reason for CodeIgniter's popularity:  Most (all?) other PHP frameworks require you to have a shell account and/or permissions to install software on the server.  CodeIgniter works with almost all standard hosting accounts.

That's the simple answer.  I'll let others express opinions on automated testing and deployment.
