I'm currently working on a PHP project and I came across the "array_udiff()" function. I've read the official PHP documentation, but I'm still a bit confused about how it works. Can someone please explain it to me with a simple example?
Here's what I understand so far: the "array_udiff()" function is used to compute the difference between two or more arrays by using a callback function for the comparison. However, I'm not sure how the callback function should be implemented and what exactly it does.
Any help in clarifying this would be greatly appreciated!
