Hey there! Well in my php code I usually read the php.net documentation, it is very complete and great when you have problems in your code. Also looking in Google or forums such as stackoverflow. I used to have a teacher that said "coding is 80% google and 20% writing". I recommend to always have a php.ini file in your php projects, this will help you because when you do something wrong this will tell you the line where the problem is. Having a good text editor or IDE with their respective plugins and linters for PHP will tell you where the error is. Actually, I think it is matter of practice. The more you write, the more you will understand your code. The problems and errors are usually repetitive and you will get familiar with them, and you will remember how to solve them. Hope this was useful to you, and remember you can contact me whenever you have a PHP problem!

Thanks! What do you mean with system scripting, and how can I learn about machine learning??

Thanks, the problem is that I don't know how to do those things

Finish the work, then ask for the money. Never give the product to the client until he gave you the money.

Thanks bro! But I'm jus starring, in a few months I'll tell you if I can apply this knowledge to my Java code😂😂

A program in Ruby. Actually a calculator. A very basic and rudimentary calculator but was functional 😂😂 Then I continued with JavaScript and the web world.

Practice everything your minds think, get informed about news, code with other people interchanging ideas. That's the way I practice. Hope was useful!

I mean JavaScript with no frameworks or libraries. Thanks for answering!

You need time and a lot of money to develop your own projects when you have a family to maintain. But you can do it in your free time🤷

You are comparing different things. CSS is a technology that helps you to give styles to your website. If you have enough knowledge,of course, you can build a responsive design. MaterializeCSS is framework that makes you easy to make a responsive design, because all the css and the other stuff was already made for you to use it. On my personal opinion I think that MaterializeCSS is a very basic framework (it's good but there is some stuff that must be developed), I would use Bootstrap that is easier to learn and there is more courses about. If you need the materialize theme for your website use materializeBootstrap. Hope was useful!!
