[pdftex] php, pdf, latex, ....

[chiari mario]

Hello,

I wonder if anybody on this list can me give me some
comments/hints/pointers on the following idea:

I would like to put a (long) LaTeX file on line (on a web server), as to
let people to choose which sections  to compile and view/download, both as
.html and .pdf.

I would like to use mysql and php. 

Is there any already developed solution?
Thanks 
mario
