Equip Framework
A tiny and powerful PHP micro-framework created and maintained by the engineering team at When I Work.
Attempts to be PSR-1, PSR-2, PSR-3, PSR-4 and PSR-7 compliant. Also uses the ADR pattern. You should too!
To get started, check out the documentation. There's also a sample project that shows the best way to use this framework and is a quick way to start a new project.
