udemy-php-cms VS no-framework-tutorial

The only thing I accept guilty for is overreaction. Sometimes yes, I can't hold it. But if you actually look at the code of those udemy courses, I'd like to see your reaction too. Did you actually look at them? Why every single one teaches you how to allow and SQL injection around overall shitty code as though it's 2003 around, not 2023? Taken from the most fucking popular PHP Udemy course out there.

I myself learned by following the great "no-framework-tutorial": https://github.com/PatrickLouys/no-framework-tutorial Disclaimer: The last one is about 7 years old, so some things have changed, but all in all the information there is still valid.

No framework tutorial

Here's an all-in-one github repo that I found to be a nice build for the fundamentals: PatrickLouys/no-framework-tutorial

Use libraries or a micro framework if you are hesitant on using a full framework. Nothing wrong with Slim and some other libraries. Or bundle some libraries together to make your own slim (pun intended) framework - like this or this.

https://github.com/PatrickLouys/no-framework-tutorial also got turned into a book.

This tutorial (and subsequently the book) helped me a lot when learning OOPHP.

Do you already know how backends work? Maybe this can be a good read. Otherwise just look up the basic syntax and some quirks and you will be fine.

Search for "PHP without a framework" to find articles such as https://github.com/PatrickLouys/no-framework-tutorial that will show you how to "fill in the blanks" with libraries or simple code, or use a "microframework" such as Slim.
