PHPixie

PHPixie started as a micro framework and has gradually grown to be one of the most popular fullstack PHP frameworks while retaining its high performance. This is in part because of the strict architecture that avoids common pitfalls such as reliance on static methods, global scope, singletons and other antipatterns, thus also ensuring that the code is easy to read, debug, extend and test. In fact all PHPixie components boast full unit test coverage. It is the PHP framework that will never stand in your way and provides you with full control over execution flow, easy to learn and straightforward to master.

But it's not all just about the code. The PHPixie community is very friendly and helpful, you can expect getting an answer to your question within minutes of asking it in the chat. The framework documentation is full of examples and is regularly updated with tutorial videos.
