Swiss Ephemeris PHP: A 1:1 FFI Wrapper for Astronomical Precision in PHP 8.3+

Swiss Ephemeris PHP: A 1:1 FFI Wrapper for Astronomical Precision in PHP 8.3+ If you have ever built an astrology, astronomy, or ephemeris-based feature in PHP, you probably know the common trade-offs: CLI wrappers, slow process spawning, text parsing, or incomplete pure-PHP approximations. I wanted something better. So I built Swiss Ephemeris PHP — a framework-agnostic FFI wrapper for the Swiss Ephemeris C library, designed for PHP 8.3+, with prebuilt binaries to make installation easier across platforms. This package is meant to stay close to the original Swiss Ephemeris API. No unnecessary abstraction. No external CLI process. No text-output parsing. Just direct native function access through PHP FFI. What is Swiss Ephemeris? Swiss Ephemeris is one of the most widely used astronomical calculation libraries for planetary positions, sidereal calculations, house systems, eclipses, and more. It is trusted for high-precision astronomical and astrological work, which is exactly why it is
