What technologies to use for comfortable development of a web project?

Question

Project management

Task: Determine the necessary programs / frameworks / utilities for comfortable development and debugging of a web project.
Details: Let's assume that there is a project (or rather, its TK and a partially implemented core), we have decided on the technologies that we will use to implement the project (Apache + MYSQL + PHP and HTML + CSS + Javascript for the frontend). Development is carried out on a remote server.
The problem itself:It consists in the fact that I write this whole thing in Notepad ++ via FTP. The tasks there are not so complicated, so I still manage to implement the necessary part quite well. But the further into the forest, the more I understand that this is only suitable for a beginner. I have no experience in developing complex web applications. + to everything, one more person will be involved in the development of the project in the future, i.e. like a team work.
I tried to find some tips, methodologies on the Internet, but either I'm not asking Google questions correctly, or there is not so much information.
What I could find and my thoughts on this topic: To begin with, replace Notepad ++ with a good IDE - for example, PHPShtorm, it can also work via FTP. I also thought that it would be nice to use an SUV, for example git, but I'm not sure here.
So,I'll repeat the question again. Considering all of the above, please tell me what technologies should be used and how to develop and further debug a web application.

Answer 1

Don't write code on the server, learn about deployment, development and production environments to get started. Git is required, or any convenient SVN.
