Is it right to study everything at once?

Question

Programming languages

2 years ago I started learning HTML and CSS. But very lazy to study because there was not much time. Later I started learning PHP, now I'm learning PHP and JS, in addition I want to start learning Python for a course project on algorithmization. And the fact is that I know PHP and JS only at a basic level, and even without practice. Is it right to shove Python into your head as well? I started learning Js when to start getting stuck in php, because while studying js I began to understand how some things work in php, but still I had to know at least something about js. Is it right to "learn everything at once"? The main problem is that I can write at least some site on html and css, but I haven’t even practiced on php and js and I’m going to start learning Python right away.
As a bonus, I would also like to know what mini-project can be made using both php and js. :|

Answer 1

You are doing everything right, but not enough. Here is a short list of languages ​​that you should start learning right away.

Answer 2

learning something is useless, you need practice and not cramming.
throw away all the textbooks gathering dust on the shelf, they are not effective, come up with a project for yourself and start doing it, and where you have already fallen into a stupor - go to reference books and textbooks, so the profit will be many times greater,
well, about spraying several EPs at once, too it’s not worth it, there will be porridge in your head. it’s better to train thoroughly in one thing, and then look at the rest for general development,
otherwise mess will appear in your head, you don’t study English, German and French at once, do you? Well, it's the same with programming languages.

Answer 3

As a bonus, I would also like to know what mini-project can be made using both php and js.

This is exactly where you should start. Take a simple project and make it in PHP + js. I usually suggest making a simple online store.
1. On the left in the sidebar, categories and subcategories
are displayed 2. On the right, products are displayed: name, picture, description, price, "Add to cart" button, for the admin "Editing". When you click on a category, only the products that belong to it are displayed.
3. Make for the user editing the cart and confirming the purchase
4. Make an admin page of the report in the context of categories and months.
Such a project will teach you HTML and CSS and MySQL and PHP
======
When done and feel confident, before switching to other languages, rewrite this project with one of the PHP frameworks, for example, Laravel. Then you can move on to other languages ​​if you wish. Otherwise, it will be running around on surfaces without moving in depth.
