Passing Arrays between scipts

[Anon]

I'm trying to create a directory that will create a random list of links that I will be pulling out of a MySQL db. Since there are potentially thousands of links, I want to split them up into pages. My idea is to create an array of uniquely random numbers which will correspond to ID positions in the the db, but i'm going to need to pass this array from PHP script to script (so that every link is shown only once). How can I pass an array from one PHP script to another? Passing it through the querystring would be way too long, so I was thinking about using POST, but how would I go about doing that? Or perhaps this is entirely the wrong way of going about it. Suggestions please.

If you really want these random, do this:

run a cron that populates a table of foreign keys in a random order daily or even more frequently, but daily would be best. You can then run a mysql query with limit X, Y and join your links table to your random order table. Then store the position with the random order table in the session or in the get.

That's a great idea. I'll try that right now. Thanks a bunch!
