    这些函数的行为受 php.ini 中的设置影响。

    这是配置指令的简短说明。

    ffi.enablestring

    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.

    ffi.preloadstring

    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 FFI::scope().
