Is there a way to improve this php code?

I am relatively new to OOP in python and am making a little program to get me started. The problem is that when I create an object, no matter how many positional arguments I use, I seem to have an error with the number of arguments.

As I'm fairly new to this area of programming, I'm not quite sure what to try, but I have attempted to play around with the attribute initialising stages, however, that completely disables the program.

There is a white burger menu. The problem is that in my project in some places of the site it is not visible due to the opaque background. The task is to write a script that should change color depending on the background color to a contrasting color. In the code below, for example, on a black background, the menu should turn white. The original plan was to assign a different id to each block, and when the menu icon hits a new section, it changes color. But due to poor knowledge, js did not work. Also link to codepen:

I'm trying to create a sort button of a certain data so that I could sort them ascending, but there is an error inside the coding, where do I need to start? thank you

1)I tested my code on https://www.tutorialspoint.com/compile_c_online.php It somehow works by showing the ideal output of 1,3,27,23,19 but gives me the error message too which is strange since all my functions didn't have any integers. Can anyone tell me why the line shown with the error is wrong?

2)I suspected it has to do with the character ' not being handled properly, but I do not know how to print out all the special characters other than %% and \\. Can someone direct me to a full list of them?

Edit: I realised there's actually 2 escape characters I got wrong(found the proper term for it on https://www.geeksforgeeks.org/escape-sequences-c/), which is both the single quote and double quote. Are there anymore other than this list?

I have a need to remove 'ghost' entries from the PackageRegistrations of my software deployment GPOs.

What I mean by that is that there are more entries in the ADSI object than there are MSI/MST files associated to the GPO. i.e. what this blogger also seems to be experiencing http://justanotheritblog.co.uk/2016/11/15/list-msi-paths-from-software-installation-policies/ (I just found this when looking into my issue).

When nosing around the properites in ADSI, I stubmbled across 'msiScriptName', which seems to have a value of either 'A' or 'R'.

What I cannot seem to find, is any information as to what these values may represent.

Any ideas on what the 'A' and 'R' mean and/or how to correctily identify and/or remove the 'ghost' entries greatly recieved.

The reason for this is that I have a whole bunch of software deployment GPOs that need the file path updating, and rather than manually editing each one I wanted to use PowerShell to bulk update them - we are moving to DFS from fixed file server, so I need to update the msiFileList properties. This I can do, but do not want to waste processing overhead on irrelevant objects.

The following is rough code suggesting how I am doing this
