ffi.enable
string
Allows enabling ("true") or disabling ("false") FFI API usage, or restricting it only to the CLI SAPI and preloaded files ("preload").
The FFI API restrictions only affect the FFI class, but not overloaded functions of FFI\CData objects. This means that it is possible to create some FFI\CData objects in preloaded files, and then to use these directly in PHP scripts.
