Arrays in PHP: surprising results when adding new items

So I'm writing code that allows me to collect images collected by the Instaloaderpython library and put them into a gallery on my website. I've managed to collect and display these without any problems, however I've now started implementing headers for each post and I'm running into issues. The way the library downloads photos is that if there is more than one photo in the collection, it will add _1, _2, etc. suffixes to the post based on the location of the image in the collection and provide the .txt file as a title. Example folder contents for collection: 2022-12-26_14-14-01_UTC

How to get openid after scanning the QR code image generated with PHP?

I used the PHP QR code generation class library to generate a QR code picture (not generated by the WeChat interface). I want to get the openid of a WeChat user after scanning the QR code. How can I implement this function? (I previously thought of using web page authorization to achieve this, but the prerequisite for this is that WeChat users need to pay attention to the official account. Is it possible to directly scan the QR code to jump to the target page without users paying attention, and obtain it in the process? to his openid?)

Below is the code snippet of the server database initialization connector in the application fromfastapiimportFastAPIimportmysql.connectorapp

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. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
