in reply to julian below: a) this is not really related to fork() b) a much more elegant method is to avoid the race condition on the server-side, with an atomic check and update operation: update queue set worker_id=$id,status='processing' where worker_id is null and status='free' select * from queue where worker_id=$id -- we now either have our job to process, or got none and sleep/try again you might also do away with the status column if you delete jobs that are done, or use affected_rows() to check if you grabbed a job successfully ---- Server IP: 212.124.37.9 Probable Submitter: 89.204.137.105 ---- Manual Page -- http://www.php.net/manual/en/function.pcntl-fork.php Edit -- https://master.php.net/note/edit/99334 Del: integrated -- https://master.php.net/note/delete/99334/integrated Del: useless -- https://master.php.net/note/delete/99334/useless Del: bad code -- https://master.php.net/note/delete/99334/bad+code Del: spam -- https://master.php.net/note/delete/99334/spam Del: non-english -- https://master.php.net/note/delete/99334/non-english Del: in docs -- https://master.php.net/note/delete/99334/in+docs Del: other reasons-- https://master.php.net/note/delete/99334 Reject -- https://master.php.net/note/reject/99334 Search -- https://master.php.net/manage/user-notes.php
