asynchronous queue in php

Question

PHP

Good day. There is a curved parser for specific tasks, curl_multi is used and a batch of url lists are fed to it.
the remote side sometimes slows down and I have to wait for completion for the whole pack
; I see a crutch implementation with workers - give each url to a third-party script and wait until it responds, but I don’t know how correct this is and how to control execution. maybe there are ready-made examples?
that is, having three urls
with a long answer from, say, the first one and with 2 and 3 completed, start accessing 4 and 5, and after the first one answers, start picking up the sixth one.
sorry for the confusion, in short, I'm looking for a ready-made class or a sane description of how to write multithreading with a queue
thanks
