I've been using PHP for some time now, and I recently came across the `ob_get_level()` function. I've read the documentation, but I'm still having a bit of trouble understanding how it works and what it's used for.
From what I gather, it seems to be related to output buffering in PHP, but I'm not quite sure how it fits into the bigger picture. Can anyone explain to me what exactly `ob_get_level()` does and provide an example of how it can be used in a practical scenario?
I would appreciate it if someone could shed some light on this topic for me. Thank you in advance!
