Hi,

Difficult. This involves polling from the client, starting a fresh
process that may run for ages, and making sure the polling clients gets
the info that the report is ready.
Can be done, but I would prefer to take another (less errorprone) route.

I think I would chicken out as follows (just an idea):
1) tell the visitor to give an emailaddress. (where the report must go)
2) Store in your database the details you need to generate the report,
along with the emailaddress.
3) Make a cronjob that runs every 5 minutes and calls some php-file that
checks if a new pdf-generating job is stored in the db.
4) If so, run the pdf-job, email the result, and flag the job as done.

That way you only use 'standard' buildingblocks and do not have to start
new processes. (At least what I consider 'standard buildingblocks').

just my 2 cent.
