I hope you're all doing well. I have a question about the PHP `chmod()` function and I was hoping someone could help me out.
I'm currently working on a project where I need to manipulate file permissions programmatically using PHP. After doing some research, I came across the `chmod()` function, but I'm not sure I fully understand how it works and how to use it correctly.
Could someone please explain to me what the PHP `chmod()` function does and provide an example of how to use it? I would really appreciate it if you could also explain the different parameters that can be passed to the function and what they represent.
Here's a bit of personal context for my question: I'm developing a web application that allows users to upload files and share them with others. As part of the file management system, I want to give users the ability to specify who can access their files by manipulating the file permissions. However, I'm struggling to accomplish this using PHP.
Thank you in advance for your help!
