PHP curl batch processing realizes controllable concurrent and asynchronous operations

This article mainly introduces the controllable concurrency and asynchronous operation of php curl batch processing. It has certain reference value. Now I share it with you. Friends in need can refer to it.
The examples in this article are described PHP curl batch processing implements controllable concurrent asynchronous operations. Share it with everyone for your reference, the details are as follows:
Usually cURL in PHP runs in a blocking manner, which means that after creating a cURL request, you must wait for it to execute successfully or time out before executing the next request: API CURL is generally preferred for interface access. In actual projects or in the process of writing your own gadgets (such as news aggregation, commodity price monitoring, price comparison), you usually need to obtain data from a third-party website or API interface. When processing a URL queue, in order to improve performance, you can use the
curl_multi_* family of functions provided by cURL to achieve simple concurrency. <pre class="brush:php;toolbar:false"><?php
