I hope you're all doing well. I have a question regarding the PHP `filesize()` function and I was hoping someone could help me out.
So, I'm currently working on a web application where users can upload files, and I need to be able to display the file size to them. After doing some research, I came across the `filesize()` function in PHP, but I'm not quite sure how to use it correctly.
I understand that the `filesize()` function returns the size of a file in bytes, but I'm unsure about the syntax and how to implement it in my code. It would be great if someone could provide me with a simple example of how to use this function.
Let's say I have a file called "example.txt" stored in the same directory as my PHP file. How would I use the `filesize()` function to retrieve the size of this file? Can I directly pass the file name as an argument to the function, or do I need to provide the file path as well?
I also have another scenario where the file is stored in a different directory. How would I modify the function to account for this?
Any help or guidance on the proper usage of the `filesize()` function would be greatly appreciated. Thank you in advance!
