I have been working on PHP and I came across the `closedir()` function. I have read the documentation, but I need some clarification regarding its usage.
I understand that `closedir()` is used to close a directory handle that was previously opened with `opendir()`. However, I'm not sure when exactly I should use it and how it can help me in my code.
Could anyone provide me with a real-life example where the `closedir()` function is used? It would be great if you could share some code snippets to demonstrate its usage. Additionally, I would also appreciate any tips or best practices related to `closedir()`.
Thank you in advance for your help!
