sh
    //walker() - Walk recursively through the structure

    $struct = array("casa"=>2, "cafeina"=>array("ss"=>array("ff"=>21, "ff1"=>22)), "oi2"=>5, "1"=>"", "ss"=>"dddddf");

    $treewalker->walker($struct, function(&$struct, $key, &$value) {
        //Removing element
        if ($key == "ff") {
            unset($struct[$key]);
        }

        //changing element
        if ($key == "ff1") {
            $value = array("son" => "tiago");
        }
    })

    Output:
    {"casa":2,"cafeina":{"ss":{"ff1":{"son":"tiago"}}},"oi2":5,"1":"","ss":"dddddf","time":"0 miliseconds"}


sh
    //getDynamicallyValue()

    $struct = array("casa"=>2, "cafeina"=>array("ss"=>array("ff"=>21, "ff1"=>22)), "oi2"=>5, "1"=>"", "ss"=>"dddddf");

    Static access:
    $struct["cafeina"]["ss"];

    Dynamic access:
    $treewalker->getDynamicallyValue($struct, array("cafeina","ss"));

    Output:
    {"ff":21,"ff1":22}

    //setDynamicallyValue()

    $struct = array("casa"=>2, "cafeina"=>array("ss"=>array("ff"=>21, "ff1"=>22)), "oi2"=>5, "1"=>"", "ss"=>"dddddf");

    Static access:
    $struct["cafeina"]["ss"] = "newvalue";

    Dynamic access:
    $treewalker->setDynamicallyValue($struct, array("cafeina","ss"), "newvalue");

    Output:
