Stupid question: Why do I need a development environment and what is it even (Wikipedia is unclear)?

Answer 1

The development environment is needed to facilitate, simplify the development process. Briefly.
In fact, you can write code in notepad. Let's take python for example. If it is not indented there, then the code will not be executed as it was intended, if it is executed at all. And the IDE takes care of it.
In the same php from tags - the development environment can auto-complete the name of the variable, which will speed up the process of typing code and avoid banal typos.
This is all just the tip of the iceberg. Modern IDEs do tons of things to make the programmer's job easier.

Answer 2

Well, roughly speaking, you will only see a syntax error without an environment on the server, otherwise it’s right in the environment or the editor, and there some still have FTP attached at once to upload all files to the server at once.
