4. Phalcon-JWT: Used for the creation and parsing of JWT tokens, which can easily implement API authentication.

4. Conclusion

The Phalcon7 framework is a high-performance PHP full-stack framework, which has many advantages such as fast performance, complete component modules, simplicity and clarity, and high security. Before using the Phalcon7 framework, you need to install extensions and a running environment. The Phalcon7 framework provides a series of powerful components, such as controllers, models, views, and routes, to help developers quickly build Web applications.
