NASA/JPL CUSTOM EPHEMERIS TOOL - EXPERIMENTAL

AUTHOR   : Jay Tanner - 2025
LANGUAGE : PHP v8.2.12
LICENSE  : Public Domain

The purpose of this program is to allow users to create customized ephemerides
or astronomical almanacs and other tables based on the NASA/JPL Horizons API.

The code cab be used as a tutorial for other PHP programmers who wish to use
the Horizons API for their own custom PHP web software.

USING THIS PROGRAM LOCALLY


This program can be run on a local PC web server like XAMPP, which is what I
use at home to write and test the software, currently using PHP v8.2.12.

When I wrote the program, I tested it on my home PC and the HOME coordinates
are for my home in central New York State, USA.  To use it from your home,
you can simply change the time zone setting and  the home coordinates to your
own GPS location.

To use it on an Internet web site, users can set the time zone and coordinates
for their location which will be stored in a local cookie until deleted.  This
way users won't have to reenter their location data for each computation.
