Well, it's easy enough to pass variables on from PHP to Perl or vice versa, or onto Flash for that matter. I don't really see what the problem is in regards to 'integration'. Both can also use the same backend system and the same databases.

If I really wanted to I could engineer a multi-page form consiting of:

First page in PHP -> second page in perl with all variables passed to it from our PHP page -> third results page in flash with variables passed to it via the Perl page.
