php - How can I do time consuming task after sending response to client

Question

The scenario is: when a user upload a image, we do image resizing on the server, but instead of waiting for this job done, I want it to response to the user immediately. if there is a thread available, I would properly just use thread to do this task, but as far as I know , there is no thread in php, so how can I achieve this goal? Thanks for ideas and suggestions.

Either fork the process (ugly and unreliable) or use a JobQueue, like Gearman.
