A friend of mine never went into a classroom but he now understands most of the programming languages. How hard is it to do this on your own? Does anyone know of any such websites that give tutorials?
I have been slowly teaching myself how to code, from designing my own website and learning as I went. It's really easy to find out all you need to know seeing as how most of the information is there online and on Youtube for free.
PHP has an online repository with code samples. If you look at php.net, you can check which commands you are using, and how to use them. If you've never seen php before then https://www.w3schools.com/php/ has a beginner's course on it, although it assumes you know some HTML.
