#11224 — Best strategy for creating an application scoped variable?

Hi,

I'm using PHP 5.2.  I would like to populate a hash from a database
query.  The hash should be available to all users of the application
and would only be updated very occasionally.  The database query is
expensive, and I would prefer only to run it once, whenever PHP was
restarted, or on the rare occasion when the database data changed.
What is the best strategy for implementing this hash?

Thanks, - Dave

I'm confused. What "hash" do you want to "populate"? Do you just want to
stick a pregenerated value in a table? Maybe you need an insert/update
trigger?

    rope-bridge over a river of lava is not even worth considering.)
