I hope you are doing well. I have a question regarding the PHP function is_dir(). I have been trying to understand its usage and how it works, but I am a bit confused. I have gone through the PHP documentation, but I would appreciate it if someone could help me with a clear explanation.
I have come across this function while working on a project that involves handling directories in PHP. From what I understand, is_dir() is used to determine whether a given path is a directory or not. But I would like to know more about its functionality and how it can be used effectively in real-world scenarios.
If any of you have used this function before and have some experience with it, could you please share some insights or provide an example of how it works? It would be great if you could explain any potential caveats or common mistakes to avoid while using is_dir() as well.
I am particularly interested in understanding how to use the is_dir() function to check if a specific path represents a directory, and how to handle situations where the path does not exist or if there are permission issues.
Thank you in advance for your help and guidance. I truly appreciate it.
