Here’s an interesting solution<\/a> for a poor man’s asynchronous queue using PHP-FPM:<\/p>\n

PHP-FPM already acts as a queue for Nginx\/Apache FastCGI clients. While your web-request is running you can just send another FastCGI request to the same PHP-FPM socket asynchronously and non-blocking. This request is immediately executed in another php-fpm process in parallel and you could wait for it to complete or just fire and forget.<\/p><\/blockquote>\n

Given the experimental nature of this approach, you probably won’t be running this in production. \u00a0And with many developers switching to the built-in PHP web server for the local development, this doesn’t work for those environments other.<\/p>\n

But it makes me think what else can be used as a queuing mechanism. \u00a0After all, there are plenty of systems that rely on this already – email servers, printer spoolers, web and proxy servers, and probably more.<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
