The ORM framework is a solution that encapsulates ORM technology into a framework and provides a series of methods and classes to operate the database. The main purpose of the ORM framework is to simplify database operations and improve code readability.

Laravel is a very active community, and Eloquent, as an important part of it, has been widely used and updated, so it will continue to be used in the future. You can look forward to updates and improvements to Eloquent.

4. Summary

As a very popular programming language, PHP also has many choices in the field of ORM framework. Although each framework has its advantages and disadvantages, we strongly recommend using Eloquent. Its simplicity, ease of use, flexibility, and active community can greatly improve development efficiency and code readability.
