Master: How long does it take to learn to use PHP to make a purchase, sales and inventory, and what do you need to learn?

That's right, for a mediocre person like me, you are the masters. I am an office worker, working in a traditional manufacturing industry. I don’t work overtime. I have about 3 and a half hours a day after get off work to study, and I have a little basic knowledge of CSS. I have always wanted to make up my mind to learn PHP, but I never started learning it. But now I want to use it to manage daily shipments and warehousing of product warehouses. Many software are difficult to use or very expensive. So I want to learn by myself.

How to add login verification to the backend templates on and off the website?

The website provides many templates for the backend management system, all of which are in HTML. I have only learned PHP jump verification. I would like to ask how to add login verification to HTML. It seems that PHP's $islogin cannot be added to the HTML file. Judging, the session cannot be read, so if the user directly opens the html web page, how to judge a non-logged in user and let him jump to the login page. If it is ajax verification, do you also use session or how to judge?

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops.
