A long running process (daemon written in PHP or something done with <code>Node.js<\/code>) reads a queue of tasks (from database \/ nosql, whichever you&#8217;re familiar with) and executes tasks.<\/p>\n<p>Frontend-facing PHP simply fills the queue and notifies the client that job has been queued without actually doing the work.<\/p>\n<p>That way you can have multiple workers performing long-running tasks by reading from same job queue source. Even if one dies or something else bad happens, you can always resume the work by restarting the worker process.<\/p>\n<\/p><\/div>\n<div class=\"mt24\"><\/div>\n<\/div>\n<p>            <span class=\"d-none\" itemprop=\"commentCount\">2<\/span> <\/p><\/div>\n<\/div>\n<p>[ad_2]<\/p>\n<p>solved How to add pthreads to MAMP PRO PHP <\/p>\n","protected":false},"excerpt":{"rendered":"<p>[ad_1] This question was an XY problem and it didn&#8217;t deserve so many downvotes.
