Would that be the > way? I would tend to not start it from PHP, but to write enough details into a "queue" table which would be processed in sequence by a background task. This approach: a) simplifies your PHP a bit, b) avoids the issue of 'when' entirely, c) lets you write status into the queue table and have a page that tells them it's 50% done, or is next in the queue, or whatever, and d) makes the handling of 10, 20 or 30 minute jobs one which hits the database serially, rather than in parallel (or you can control the parallelism to a level your equipment can handle).
