includeing c (BLADE)

I have been working for the last fiew months to create a web based environment called BLADE (http://www.thestuff.net/bob/projects/blade). Many people have their own language preference for createing CGIs and many good CGIs cant be used with each other because of look&feel, and they just dont communicate very well with each other. I created BLADE to allow any language to communicate with each other, so you could do something like, create a BLADE object in perl and embed it within a python page. Well, my favorite choice for web development has allways been php. I would like to add php suppport to BLADE, but I have yet to find a way to create a php c lib and include it. Since BLADE is still under development, I would prefer it not to be compiled directly into php since if there is a core dump in LibBLADE, it could take down the whole web server. What is the best way of creating php functions in c? Could someone point me to a document if one exists? Thanks, Bob Smith
