    You can also pass function object as argument of LuaSandboxFunction::call():

    $lua = new LuaSandbox();
    $phpLuaFunction = $lua->wrapPhpFunction(function ($arg){
    echo "LUA> ".$arg;
    });

    $lua->loadString("print = ...")->call($phpLuaFunction);

    $lua->loadString('
    print("print test from lua\\n")
    ')->call();

    result:
    LUA> print test from lua
