PHP Dice Roller with numerous Shadowrun functions, Plans to add, email, database, and social networking Options

[Lilt]

Yesterday, I happened upon igoogle, which got me thinking about making some gadgets for it. Using the iigoogle gmail gadget to keep track of some PbP games I'm in gave me an idea for a social networking app to aid in running PbP/PbEM games. You'd have the app open in whatever social networking site you happen to use (facebook, bebo, myspace, okrut, igoogle). It lists the on-line games that you're in, and keeps-track of some stuff like character names, systems, and basic character stats (or just tracking common rolls) to offer a streamlined rolling interface.

Although I could make a js gadget that created random numbers and did everything, unfortunately that would not be able to rule-out cheating. What I've thus decided to do, in the interests of ruling-out cheating, is to create a PHP/MySQL dice server/verifier. As a dice rolling system isn't much without a dice roller, I decided to make that bit first. It's got a web front-end right now, but it's modular so the same dice roller will be used regardless of whether it's being called by a gadget, an app on facebook, or some standalone game running software.

It's still in its infancy, I got the web space and started coding less than 12 hours ago, but I'm quite proud of what the dice roller can do in its current state so I decided to share it with you. It does most (i think all?) of the tricks necessary for SR3 and SR4 dice rolling, and can even be tweaked for house rules.

Here ya go:

Unfortunately, that free hosting site seems to have disappeared. I'm now hosting it on:

I'm less interested in bugs right now, there will be lots of them. Right now I'd like some feedback on the syntax I'm using, and if there are any features you'd really like to see that I've not mentioned already.
