I’ve decided to take a look at how things got to this point, and what can be (and is being) done about it. I start out pretty gloomy, but bear with me; I promise it gets better. In the Beginning, There Was Apache and CGI And there was much rejoicing. In 1994, Rasmus Lerdorf created the “Personal Home Page Tools,” a set of CGI binaries wri...

It is frequently used to store static data so that they can be loaded when needed. But as per spec, it says that the keys and the values are always strings (note that, as with objects, integer keys will be automatically converted to strings). Why cannot store the object as it is?
