这是配置指令的简短说明。
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 <span class="classname">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.
ffi.preload string
Allows preloading of FFI bindings during startup, which is not possible
with FFI::load if
opcache.preload_user is
set. This directive accepts a DIRECTORY_SEPARATOR delimited list
of filenames. The preloaded bindings can be accessed by calling <span
class="methodname">FFI::scope.
