Example of how to implement socket communication between PHP and Python

This article mainly introduces the PHP implementation of the socket communication with Python method, combined with an example of PHP to use the custom class to send socket request data and Python to receive socket data and processing requests and other related operations skills, the need for friends can refer to the next

The example in this paper describes how PHP implements socket communication with Python. Share to everyone for your reference, as follows:

Design Purpose

Send a request to php,php to create a socket request to the Python script via the front-end page, and then return to the front end after execution is complete.
