How to create a visual editing website in PHP?

Question

Learned a little bit of php development.
I have seen many visual editing websites on the market. Register as a member and select a template to edit. The web page is highly operable.
I studied it for 1-2 weeks with a learning mentality, and found that I had no foundation at all. I found several sets of source codes to learn, most of which were encrypted. I looked at the discuz forum, and it was quite complicated, so I didn’t understand it.
Please ask me, what basic knowledge points should I start with?

Answer 1

For personal blogs, you can check out WordPress and for cms, look at DreamWeaver

Answer 2

These require a lot of front-end knowledge. Of course, we must start with the basics of the front-end.
