I'm needing to send a (rather large) array FROM AS2 to PHP in the form of a link, and then have AS2 read the array from the link. I know how to read variables from links and whatnot, I just need to know how to read/send an ARRAY.

Thanks.

Could you use a SQL database? Otherwise you can convert it into something like a CSV and send that file.

How about something like JSON?

Yes, JSON. You want the php script to act as a web service, basically.
