Convert array with key in dot notation for multidimensional array

                $last = &$last[$dot];
            }

            $last = $value;
        } else {
            $newArray[$key] = $value;

}

This is not exact, but is realted. Here are simple getter and setter functions to allow using a single string, dot notation path for accessing multidimensional properties in PHP. E.g. "prop1.prop2.prop3"
