Compiling your own PHP extensions?

A bit more background as to why I need them :) I can't believe I only just came across this library now :) I spent the later part of last year writing an online stockmarket analysis application in PHP. Since I didn't know c++ in detail I had to write all the data import and analysis routines in php. This obviosuly would generate quite a bit of speed difference to my import routines. 2-3 hours for the australian stockmarket. Recently we tried to get someone to convert my php routines to c++ but they didn't quite get it right. So my main question is has anyone integrated this into the PHP source code. I would love to be able to use these routines in my php scripts. If noone has, is anyone willing to write it? I am sure I can get my boss to chip in some dollars.
