A modern approach to developing an MVC framework in PHP (REST, security, performance, etc.) - what to read?

Question

PHP

interested in articles, books, manuals

Answer 1

Read the source code, articles on existing frameworks. In general, this is not necessary, just use the existing ones.

Answer 2

Something tells me that in order to write your own framework, you need to know the shortcomings of existing ones. After these shortcomings are identified, a product is designed that is devoid of these shortcomings. To identify the shortcomings of other frameworks, you need to know them from the inside, and if you know them, then this question would not exist.
L - logic.

Answer 3

Start with the documentation for the frameworks, then read their code.
No other types of information can match code.
But I warn you right away: first learn how to use this tool, and only then read the source code.
Otherwise, you just won't understand.
