Curl non-blocking call class [PHP]

I have written an article about non-blocking PHP calls.ArticlePHP implements the non-blocking mode. In fact, if it is only HTTP, it can be implemented directly using curl.

OnlineCodeAfter modification, a non-blocking call class that supports post/get is encapsulated.

Test the bug ~~~~~
