SVG and PHP

Hello to all.

First of all, sorry for my poor english. I'm spanish, and have a little idea of talking english, but I'll try to be understood.

I'm new in SVG, but I think it will be a good tool for my project. I'm designing a strategy-game in PHP-MySQL, and although I have advanced a lot in it, I have the problem with the maps. They would have to "colour-update", showing the owner of the territories. For example, I have a medieval map of Ireland. Suppose kingdom A conquest province number 10. This province has the following code.
<rect x="840" width="140" y="290" height="40" font-size="18" fill="#000000"/>

#000000 was the colour of the ancient owner, but, as the province has been conquest, the province would have to show new kingdom colour (lets say #FFFFFF).

Could I say something similar to this to get the right colour?

<rect x="840" width="140" y="290" height="40" font-size="18" fill=

<?php

....script to get the right colour

?>

/>

If I can't, is there a possibility to make it to work with PHP-MySQL just to work in game?



Thank you very much.
