php-ffi - Foreign Function Interface
- Remi's RPM repository <https://rpms.remirepo.net/>
FFI is one of the features that made Python and LuaJIT very useful for fast
prototyping. It allows calling C functions and using C data types from pure
scripting language and therefore develop “system code” more productively.
For PHP, FFI opens a way to write PHP extensions and bindings to C libraries
in pure PHP.
