Persistent Variables

Anon

Is there a way to create persistent variables visible across scripts? Cold Fusion has Application variables, mod_perl allows persistent variables, but I can't seem to figure out how to set them in PHP.

For example, I'd like to load up a list of airports and their codes, which very rarely change. I know I could load the array, serialize it, save that somewhere, and deserialize it at the beginning of each script (or each one that needs it), but I'd rather just load the array once and have it available.

Is this possible? I'm new to PHP, but need to convert some Cold Fusion scripts and am very enthusatic about PHP4.

Thanks!

Hi... I've found the best way to keep persistant variables is by putting them into a session object.

Here are the functions you'll need:

http://www.php.net/manual/function.session-start.php
and
http://www.php.net/manual/function.session-register.php

Remember:
Any time you want to access the session vars you need to put <? session_start(); ?> at the top of your page.

Good luck,
Rob

Sessions will do the trick. You can learn all about them here:
