tagreader | use NFC tag reader

I need some help please, have tried but am not even close to thinking about winning.

I need to get the ID3 PECL running on XAMPP(v7.4.5) for Windows.

I have spent the day yesterday trying to work through the PECL articles on the PHP.net website and it unfortunately does not make much sense to me, as my knowledge is not on that level yet. I have also tried looking for a dll file for the ID3 extension, but cannot find any. Only the source files are available for download for the ID3 PECL page.

Is there perhaps someone with enough patience who can explain the process in more layman's terms... dumb it down for me as it were?

Any and all help would be greatly appreciated.

EDIT

Can someone be of assistance?

With the help of Lelio I now have a way to extract info from an MP3, I have added two lines to access the Genre as well as Attached Picture blocks. The Genre block works. The Attached Picture block however, does not.

Here is the updated code which is saved as a separate php file called script-mp3-tag-reader.php:

I made app that detects nfc tag. All work fine, when my app is closed and i scan the nfc tag with my phone it shows me an activity have onCreate() method , when i scan again for the 2nd time it works , i dont know if im wrong in the lifecycle of the app or that i missed something in my code? when i open app , scanning is working : 1st photo when app is closed 2nd photo : from 2nd photo but in the 2nd scan it works this is my code

I am trying to populate parent objects with child object that match but cannot figure out how to only display the ones that match. I manage to get the child objects and add them to the list but it displays all the child objects for the parent objects.

I have a controller class which is below. I have a TagRepository interface which extends JPA repository which I am using to save TagReader instance to my DB and it works fine when I use it in my controller class. However, when I try to use tagRepository in another class and try to save my TagReader object from there it throws a null pointer exception.

The following logic works fine.
