如何在向客户端发送响应后执行耗时的任务 [英] How can I do time consuming task after sending response to client

问题描述

场景是：当用户上传图像时，我们会在服务器上进行图像大小调整，但不是等待完成这项工作，我希望它立即响应用户。如果有一个可用的线程，我会正确地使用线程来完成这个任务，但据我所知，php中没有线程，所以我怎样才能实现这个目标呢？感谢您的想法和建议。

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.

推荐答案

分叉进程（丑陋且不可靠）或使用JobQueue，如 Gearman 。

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