cglm-php-ffi

recp/cglm binding for PHP using FFI

Tested with PHP-cli 8.0.x under Linux.

the cglm C API is encapsulated into a PHP class GLM which only contains const and static members ;
it autoinit uppon include_once("./include/GLM.php"); ;
depeding on your OS, it will try to load libcglm.so or libcglm.dll from ./lib/ (default), or from the directory defined in FFI_LIB_DIR ;
a __callStatic() method is used to call C functions using FFI. Example : GLM::vec3_normalize( $vec ); ;
if required, it is possible to override a C function by adding a public static function with the same name into the class. This can be used to simply the C API and the usage of FFI with some functions that requires pointers.
helpers can be added to the GLM:: API.

/!\ Performance :

Using the __staticCall encapsulation method makes life easier, but it represents a great loss of performance.

If high perf are required, I recommand using GLM::$ffi->glmc_xxxxx() direct calls.
