Zend/Expressive 3 – The Next Generation
0 likes364 views
The document outlines the evolution of the zend ramework, specifically the transition from zend ramework expressive version 1 to 3, with a focus on PSR recommendations. Key features introduced in each version include dependency injection (PSR-11), middleware and request handling (PSR-15), and improved error handling. It also addresses migration strategies to the latest version and highlights potential applications built with zend ramework expressive.
