What knowledge should I start learning Yii2 with?

Question

Yii

Good afternoon!
I've been learning PHP for a while, but learning wasn't easy. Now the level is not high, even very low. Using procedural php, I can write some simple blog site or an online store with a Mysql database (using PDO) and a simple admin panel.
I read a lot and realized that it would be better to study some kind of framework, and not write everything from scratch. I settled on Yii2. With grief in half, I was able to install it on OpenServer via Composer (Which also installed with grief in half).
Opened the official documentation and in a stupor. I seem to have learned so much, but here everything is a dark forest. I don't understand how it all works. I don’t understand anything, I can’t really move.
Can you tell me where I missed a step? What should I learn before getting familiar with Yii2? It's hard for me to evaluate myself. I don't understand where is the difference between my knowledge and the knowledge required to work with Yii2.

Answer 1

Learning:
1 - OOP in php.
2 - MVC pattern.
In general, I suggest you start with Laravel . His dock is more understandably documented, unlike Yii, and there is less code.

Answer 2

Starting learning PHP on the fly with frameworks is a bad idea. You will understand little. Invent your own bicycles first, modify them, delete them, create them again, finish them, etc. Start with the essentials:
- Database queries, PDO wrapper, triggers, foreign keys, lookups, indexes, etc.
- Shapes, quote escaping, HTML filter, etc.
- Data validation, including to reduce the number of repeated code
- Caching (code fragments, requests), the use of tags when caching
- Routing, all requests through index.php (how and why)
- All sorts of helpers (for all occasions )
- MVC - own implementation
- Traits, abstract classes, interfaces, namespaces, all kinds of methods, class inheritance, etc.
After you can pile anything from this set anywhere in your code - go and download a popular and well-documented framework and start writing. If you immediately begin to delve into someone else's code, then your bikes were close to the truth.
