I’m using Perl’s CGI::Session with MySQL. No problems there.
I want to incorporate some other languages, most notably PHP, to use the same session cookie. How would I do that?
Almost the entire site is in Perl, but I want to use free PHP things, like forums and mediawiki, and still use the same session cookie.
I’ve never tried this, but see the session_set_save_handler function. Some frameworks (like CakePHP) use this to store the session in a database. Maybe you could write some code to use the same session as perl, prepending this script to your forum, wiki, etc.
