The core of the FleaPHP framework is very small, but through flexible configuration, various types of infrastructure can be combined. FleaPHP's excellent customization and expansion capabilities make it truly close to the goal of "meeting various needs from simple applications to enterprise development." Applications developed using the FleaPHP framework can automatically adapt to various operating environments and are compatible with PHP4 and PHP5. Unlike many other frameworks, FleaPHP is a framework that is completely refined during actual development.
The FleaPHP framework is simple, clear, easy to understand and learn, and has complete Chinese documentation and rich sample programs. High configuration, high performance and other advantages make FleaPHP a popular framework.
