communicate c program and php

Question

I want to have a web page (written in php because it\'s what i know) that displays an input value. I want that value to be passed to a c programa that\'s already running.

Answer 1

A local socket is just a file, you'd use fopen(), fwrite(), and fclose() on it, as usual. The only difference is that you're reading from (or writing to) another process, instead of a file on disk somewhere.
