PHP + framework, is there a book on this topic?

Question

PHP

When studying the framework, I encountered 1 problem, I didn’t understand anything in the attached documentation, is there at least a small resource where it is explained in detail what each element is responsible for, or at best a book?

Answer 1

pump skills. frameworks assume that you have a certain base, not only in language syntax, but in OOP/patterns/architecture/etc.
read documentation, read stackoverflow, rape google.

Answer 2

You do not need to know and think, and even read the code of frameworks. All you need to know is how to use them (i.e. their API).
A classic example,
there is a power supply from a computer. All you need to know about it is how many watts, and how to connect it to the motherboard. You don't need to know what's inside, how it all works, what laws of physics/electrostatics apply there. You are a user, not a factory.
It's the same with frameworks. No need to look at all and bother with what's inside. Open the documentation and see what API methods are available and how to call them.
And yes, there is no such thing as "pure PHP" and a framework. In fact, when they say this, they mean that they write in PHP using the components / utilities of the framework.

A recent book "Developing Web Applications in Yii2" may be useful:
