使用PHP来限制下载速度 [英] Using PHP to limit download speed

问题描述

：confused :: confused：


我一直在寻找一个可以提供下载文件的php脚本，并限制文件传输到的速度用户。我希望注册会员的下载速度更快，而且客人的速度会更慢。


我唯一能想到的是使用header（）函数强制下载所请求的内容文件类型并将文件流式传输到用户的浏览器。然后在循环中使用sleep（）或usleep（）直到下载完成。


任何人都有任何建议或想法吗？

I have been on the quest to find a php script that can serve files for downloads and limit the speed at which the file is transfered to the user. I want a faster download speed for registered members and a slower speed for guests.

The only other thing I can think of is using the header() function to force a download for the requested file type and stream the file to the user''s browser. Then using sleep() or usleep() on a loop until the download completes.

Anyone have any suggestions or ideas?
