Preloading and FFI
FFI - Foreign Function Interface — Dmitri Stogov
🐌 Processing FFI on each request is slow, but preloading is fast! 🚀
%preload.inc%:
<?php
FFI::load(__DIR__ . '/astro-preload.h');
%astro-preload.h%:
#define FFI_SCOPE "ASTRO"
void sunpos(double d, double *L, double *M, double *ra, double *decl, double *rad);
Run:
<?php
$ffi = FFI::scope('ASTRO');
…
$ffi->sunpos(
$dayNr,
FFI::addr($L), FFI::addr($M), FFI::addr($ra), FFI::addr($decl), FFI::addr($rad)
);
