For a process that takes a long time, I usually break the user interaction
& the processing apart.
For instance, when the user makes a submission from the browser interface,
the PHP takes the submitted data and stores it someplace on the file
system or in a database. This being a quick operation, the user can be
safely notified that their submission is complete, and the user can go
about his/her business within the browser interface. Then there is a
process that runs on the server, say every minute (asynchronously from
visitors triggering the PHP script), that is looking for new data in the
location the PHP script deposits the submitted data, and processes it.
It's a bit more work than just making the PHP script execute for hours,
but it is far better use of the server's resources, and gives you much
more flexibility to alter the processing w/o affecting the user experience
(actually creating a better user experience).
