I hope you're doing well. I recently came across the PHP `filegroup()` function, and I was wondering if someone could help me understand it better.
From what I gather, the `filegroup()` function in PHP is used to retrieve the group ID of a file. However, I am still a bit confused about its usage and how it works.
Could someone please provide me with an example that demonstrates the `filegroup()` function in action? Also, it would be great if you could explain how the function works step by step, so that I can have a better understanding.
Thank you so much for your help!
