I'm having trouble understanding how to use the PHP `disk_total_space()` function. I've tried looking at the documentation, but I'm still confused.
To give you some context, I'm currently working on a web project and I need to display the total disk space of the server where the website is hosted. I came across the `disk_total_space()` function in PHP, which claims to retrieve the total size of a directory.
Can anyone please explain how to use the `disk_total_space()` function with an example? I would really appreciate it if you could break it down step by step so I can understand it better.
Thank you in advance for any help you can provide!
