Is global array possible?

[richie]

Is is possible to create an array that would be available to anybody that uses my site?

Basically, I want to create an array and let it live perpetually in memory. Now, each time somebody else visits the website, I want his processes to have access to the global array, and be able to make modifications to it.

Currently I do it from database tables, but having stuff in ram would speed things up.

Is this even possible?

Most decent DBMSs would cache frequently-used tables in RAM anyway. But you could look up PHP's shared memory facilities in the manual.

Thanks for that answer.

I initially wrote my code using mysql TEMPORARY tables. Those are supposed to remain in memory.

But then, when the tables are about a day old, they become regular tables, and are listed with all the other tables in the db. I've never understood that behavior.

I think if frequently used tables are indeed cached in memory, then I need not worry about recoding the script.
