问题描述
我有一个PHP脚本，该脚本在循环中运行了x次.该代码非常少，并执行检查.某些循环会在彼此之间的1秒钟内运行，并且会有所不同..某些循环将以最多8秒的延迟运行.
I have a PHP script which runs on a loop for x amount of times.The code is very minimal and performs checks.Some loops will run within 1 second of each other and it varies.. some loops will run with up to 8 seconds delay.
如何或在服务器上进行什么调整/调整(或指示我的专用服务器的管理员)，以将循环之间的时间减少到毫秒(或尽可能快)而不是1到8秒?
How or what can I adjust/tweak on the server (or instruct the manager of my dedicated server) to reduce the time between loops to milliseconds (or as quick as possible) rather than 1 to 8 seconds?
谢谢！

推荐答案
我个人没有使用过，但是我怀疑您需要研究使用PHP中的curl_multi *东西-这似乎允许您执行多个请求一次.
I've not used this personally, but I suspect you need to look into using the curl_multi* stuff in PHP - this appears to allow you to perform multiple requests at once.
请参见 http://php.net/manual/zh/function .curl-multi-init.php
几乎可以肯定，您的瓶颈将是串行建立HTTP连接. AFAIK curl_multi_ *函数将允许它们并行执行.
Your bottleneck will almost certainly be making the HTTP connections serially. AFAIK the curl_multi_* functions will allow these to be performed in parallel.
