Php implements the SDK extension method based on the public platform development SDK (demo). sdkdemo this article describes how php implements the SDK extension method based on the public platform development SDK (demo. We will share with you the sdkdemo method for implementing SDK (demo) extension based on the public platform for php.

This article describes how to implement php SDK (demo) extension based on the public platform. Share it with you for your reference. The specific analysis is as follows:

This extension is based on the official public Platform SDK. it is simply encapsulated to implement some basic functions (such as weather query, translation, automatic chatbots, and custom menu interfaces) for learning only. the code is as follows:

The code is as follows:
