This is a wrapper library for PHP 7.4's FFI extension.
You provide it with a shared object, and one or more header files, and it automatically generates the C structures and function signatures for you (just like doing it in C would).
Eventually, this will be more structured to provide a "nicer" interface to use the FFI itself.
Currently there are two modes of operation, an "inline" mode:
$libc = (new FFIMe\FFIMe("/lib/x86_64-linux-gnu/libc.so.6"))
->include("stdio.h")
->build();
$libc->printf("test\n");And a code generating mode:
(new FFIMe\FFIMe("/lib/x86_64-linux-gnu/libc.so.6"))
->include("stdio.h")
->include("other.h")
->codeGen('full\\classname', 'path/to/file.php');
require 'path/to/file.php';
$libc = new full\classname;
$libc->printf("test\n");The code generating mode is designed to be used in production, where you'd code generate during a build step and ship with your library.
This should now work for the majority of header files. Looking at some of the code, specifically the compiler, there is quite a bit of hard coding. So I don't expect every file to work out of the box. If you find a header file that doesn't work, just open a bug and we'll take a look.
