I hope you're all doing well. I have recently started working with PHP and I came across a function called `show_source()`. I've been trying to understand how this function works, but I'm a bit confused.
Could someone please explain to me what exactly the `show_source()` function does in PHP and how to use it effectively? I would really appreciate any examples or code snippets that demonstrate its usage.
Thank you so much in advance for your help!
