Zend Framework
Zend Framework is an open-source, object-oriented web application framework for PHP, designed to build secure, reliable, and high-performance web applications and services. It follows the Model-View-Controller (MVC) architectural pattern and provides a collection of professional PHP packages for tasks like authentication, caching, and form handling. Originally developed by Zend Technologies, it has evolved into the Laminas Project, a community-driven continuation under the Linux Foundation.
Developers should learn Zend Framework when building enterprise-level PHP applications that require robust security, scalability, and maintainability, such as e-commerce platforms, content management systems, or RESTful APIs. It is particularly useful for projects adhering to strict coding standards and best practices, as it emphasizes loose coupling and modular design, making it suitable for large, long-term developments where team collaboration and code reusability are critical.
