I hope you are doing well. I'm currently working on a PHP project and I came across the file_exists() function. I wanted to understand how it works and how I can use it effectively in my code.
Basically, what I'm trying to achieve is to check whether a file exists or not before performing any operations on it. I want to avoid any potential errors or issues that could occur if the file is missing. So, the file_exists() function seems like it could be really useful.
I would appreciate it if someone can explain how the file_exists() function works and provide me with a clear example of its usage. It would be great to see a practical implementation and understand how to handle different scenarios depending on the return value of the function.
Thank you in advance for your help!
