Maintenance: Function libraries are maintained by the PHP team, while third-party libraries are maintained by the community or individuals. Documentation: The function library provides official documentation, and the quality of documentation for third-party libraries varies from library to library. Reliability: The reliability of the function library is high, and the reliability of the third-party library depends on the library itself.
