I've been working on a PHP project recently and I came across something called "nested functions." I've heard about nested loops before, but I'm not quite sure if the same concept applies here.
What I want to know is whether it's possible to define and call nested functions in PHP. By nested functions, I mean defining a function within another function. I'm not sure if this is a common practice or even possible in PHP, so I wanted to ask the experts here.
If it is possible, could you please provide me with an example of how to define and call a nested function in PHP? I would really appreciate it. Additionally, if there are any benefits or best practices associated with using nested functions in PHP, please do let me know.
Thanks in advance for your help!
