How to run PHP and mySQL in openSUSE

Hi to all,

I'm a PHP developer and have been using xampp/wamp under Windows. I just decided to have a try at web development under Linux and would like to do this on my oS 12.3 VMware installation. I would like to know :

1- How do I run PHP and mySQL services? (Names of required packages and procedure to start the service will be helpful)
2- Where do I place my PHP files and which local URL can I use to run the PHP files?
3- Where are the mySQL database files located?
4- Any helpful information on running PHP/mySQL commands from the terminal

(5- Python too, any helpful info on how to run Python files)

I'm sorry if my questions are too many and thanks in advance for your help.

Cheers
