Yes, most extensions will need some updating, but from what I have seen, the changes needed are very small (maybe a few lines) in most cases, unless you’re porting ext/gmp or something. > Since a clean 64bit build of PHP does not need anything other than > 'integer' to support 64bit BIGINT SQL numbers, loading 32bit builds with > an overly heavy solution is just not right! I don’t see how it’s “overly heavy”. Bear in mind that several extensions (not just ext/gmp) already require GMP anyway. > 'longint' only needs an > extension to provide it, which can then be replaced by properly crafted > code for devices that already have 256bit and better maths capability > anyway. GMP provides high-performance, optimised SIMD assembly implementations for most platforms. -- Andrea Faulds http://ajf.me/
