How to implement a service that can output formula with tex parameters?

Question

Is there some open source project I can refer to?

I'm using PHP.

Anyone knows?

Answer 1

I've tried about half a dozen of the available solutions. The best I've seen is QuickLaTeX which has a WordPress plugin which could easily be adapted to other platforms. It has better vertical alignment than the other solutions. There is a list of most of the available solutions at http://sixthform.info/steve/wordpress/?p=59

Answer 2

It looks like LatexRender might do what you want.
