Joomla, PHP, SQL install?

[farfields]

I want to run a small website from my N2100. A colleague at work suggested using Joomla, whick looks OK. The install requires also having PHP and SQL also installed. I don't know what to do next...

The webserver install for N2100 includes in the manual the comment:
PHP v5.0.5 and SQL-Lite v2.8.14 Web Server
Support
You may also have PHP and SQL-Lite work together with this Web Server module.
Below is an example of how to have your PHP program retrieve SQL lite supported
information.
Create a file named phpinfo.php, and place this file under the
\\<NAS-IP>\naswebsite\www directory. The phpinfo.php should contain the
following:
<?php
phpinfo();
?>
Then, you can get information from the currently supported SQL Lite version by
using the URL: http://Web_Server_IP:81/phpinfo.php.

So, I did this and had a 'page cannot be found' error. The webserver is running OK, as I've made a small index.html which will display ok.

How do I know if PHP is already installed? Or is the webserver manual misleading?
Teh webserver manual talks about SQL-lite, but Joomla mentions install of SQL. What is the difference? Which should I actually install?

Is the install of this items on my PC where I will do authoring, or on the NAS (I presume NAS)?

thanks in advance.

partially solved.

A simple error had occured. The phpinfo.php file had a different suffix, so once corrected I got the page confirming PHP, SWL-lite, etc
