This is a very simple, naive and crude PHP implementation of a minimalist gopher server. It only opens a socket, awaits for a (single) client and displays back an informational screen. The program is about 40 lines long.
It is meant as a dumb (simplest possible) example of a gopher server for students and hobbyists to fiddle with and possibly build upon. It supports only a single client at a time for the sake of simplicity. Any evolution, improvements and fixes of this software are left to the users.
