novus | JSON-File Database For PHP | JSON Processing library

I'm a student building a PHP project trying to get product names and their respective prices (from a mysql database table) to display one after the other in a dropdown list. The customer will select one of the items, and check one or both of the check boxes before pressing the place order button, at which point their item selection, order total, and chosen gift option will display in table form on a separate page. I've gotten all of the correct info to display in the dropdown list, as well as getting the check boxes to function properly, but all of the product data is on one line, and end to end. I don't get any errors at all when I load the page. I tried it another way in which I defined multiple instances of the echo statement, which formatted correctly, but only listed the first item in the database table repeatedly. These two different approaches are displayed below:

I opened some text file first.

How do we remove or filter data using regex to remove data after an in between ? The starting point is the first date (date could be dynamic it is no the fixed) so for example 08/03/2020 and the endpoint is the last 3 in capslock string (which is also dynamic but only up to 3 characters in capital letters) for example TRU in the string below. And should ignore or remove all the data after that

I have an admin dashboard that shows a Line Chart with how many users registered each month. I am getting the data from the database and it seems to all work fine but the function is quite large and I wanted to know if there was a more optimal and efficient way to get and return the same data?

I am assigning this function to a variable and passing it to my view.

Take for example the following dataFrame: x.show(false)

So, i am developing a pretty simple website. On the computer wich i work on, i was using chromium for quite a while now, and have not updated it, so it stayed at version 67. Now, i have moved to the newest version of Chrome (79) and i became quite frustrated seeing, that all of the sudden, without me changing any code, the CSS transitions pretty much do not work anymore, it's as if it was veeery laggy. ( sometimes it registers hover on element after a very long delay, sometimes not, when it does it usually does not register the end of the hover ... ). Yet, i once again checked on old version of chromium, i even checked on IE too, and it works perfect on those browser.

Here's the html of the sidebar on which the elements i talk about are located ( it's not only on the sidebar, but i think it's the best example ):
