The OAUTH protocol provides a secure, open and simple standard for the authorization of user resources. At the same time, any third party can use the OAUTH authentication service, and any service provider can implement its own OAUTH authentication service, so OAUTH is open. The industry provides multiple implementations of OAUTH, such as PHP, JavaScript, Java, Ruby and other language development kits, which greatly saves programmers' time, so OAUTH is simple. Many Internet services such as Open API, and many large companies such as Google, Yahoo, Microsoft, etc. provide OAUTH authentication services. These are enough to show that the OAUTH standard has gradually become the standard for open resource authorization.

Function libraries and third-party libraries in PHP can extend the functionality of applications. The function library provides predefined functions that can be included through the include statement. Third-party libraries are available from sources such as Packagist, GitHub, and installed using Composer. Implement automatic loading of classes through autoloaders, such as automatic loading of the Guzzle library.
