Phpfsockopen asynchronous processing instance program

In php, the easiest way to process data asynchronously is to use fsockopen. next I will introduce the asynchronous processing based on the fsockopen function. I hope it will help you. example test. the php code is as follows :? In phpnb... php, the simplest way to process data asynchronously is to use fsockopen. next I will introduce the asynchronous processing based on fsockopen function. I hope it will help you.

Example: test. phpThe code is as follows:

 
The code for test4.php is as follows:
  
Add an asynchronous processing class that can request HTTP and HTTPS protocols, and handle 301, 302 redirection, and GZIP compression. the code is as follows.
The code for asynHandle. class. php is as follows:
