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
