How persist a simple variable for all different sessions in php?

Question

There is a very complex calculation and system health verifications that returns a numeric variable.

This variable will be displayed in every page, But I don't want to make this verification and calculation every navigation. This value should be visible to EVERY session for all users, not just one session. the most simple solution could be a global variable that would persist and be available for all sessions.

Filesytem or database are not an option.

Is that possible in PHP?

Well it's the same, cache the result the same way you would cache a query. — Keyne Viana
