Example of how php implements socket communication with python, pythonsocket

This example describes how php implements socket communication with python. We will share this with you for your reference. The details are as follows:

Purpose

Send a request to php through the front-end page. php creates a socket request and submits the request to the Python script. After the execution is complete, the request is returned to the front-end.
