I am a bit confused recently. I also want to instruct you to learn the methods.

Recently, I am a little confused. I also want to ask you to learn the methods. during this time, I have been involved in php, and I have also conducted tests on related small projects (message boards, upload tools, and so on ). If you want to continue to learn php in depth, you don't know how to start by yourself, and most importantly, it is said that to learn php well, you must first be familiar with html + css (I am not particularly skilled in html + css). I must first learn html + css well and then be confused recently, I would also like to ask you to learn the following methods:
During this time, I got in touch with php and also tested related small projects (Message Board, upload tool or something ). If you want to continue to learn php in depth, you don't know how to start by yourself, and most importantly, it is said that to learn php well, you must master html + css first (I am not particularly skilled in html + css). Do I have to learn html + css first and then php again?

No, learn directly, focus on data processing, rather than style. The basic labels will still be better. I have never met div labels and learned php from the peak. haha

It is not said to be anything, but in the future, if you want to work in this area, you will inevitably have to deal with html, css, and js. Originally, these things belong to front-end development work, but how can we find it clearly in this year? in the future, not only do you need to get this information, but also SQL, that is, database, and so on. If you simply want to learn php, you can basically say that you don't need to keep up with any of the above.

Web development. Itself. These are all coming soon. Understand what you do. Engage in php. Learn php first. The notebook is used to learn other things. Have time to study carefully

Two magic weapons to teach you:

1. baidu and google
2. Reference Manual such as w3cschool

Tags, div + css, are cloud float, and they are the lives of UI designers. keep yourself for a few days, and then imitate your brother's website.
Php focuses on data and business logic processing, database operations, files, xml, operations, and framework usage,
That is the core of technology.

Give me some points. I have a serious shortage of points.
