You are confused. Static objects are constant within the request, but
they do not persist between requests.

A new instance. Here is a better way of thinking of static in an OO
context. Static properties are similar to namespaced global variables;
static methods are similar to namespaced functions.

You can refer to them anywhere within a script without worrying that
they might vary from instance to instance. (i.e. based on specific
instance data.)

You cannot set a value in one request and then access it in a second
one. As Dan says, that's what a database is for.
