简介

This extension allows the loading of shared libraries (.DLL or .so), calling of C functions and accessing of C data structures in pure PHP, without having to have deep knowledge of the Zend extension API, and without having to learn a third “intermediate” language. The public API is implemented as a single class FFI with several static methods (some of them may be called dynamically), and overloaded object methods, which perform the actual interaction with C data.

注意:

The FFI extension does not render the classic PHP extension API obsolete; it is merely provided for ad-hoc interfacing with C functions and data structures.
