I hope you're all doing well. I have recently started learning PHP and I came across the `sizeof()` function. I have been trying to understand how it works, but I'm still a bit confused. Could anyone please explain to me the purpose of the `sizeof()` function in PHP?
I would really appreciate it if you could provide some examples to illustrate its usage. It would be great if you could also mention any special considerations or limitations to keep in mind while using this function.
Thank you so much for your help in advance!
