I hope you're doing well. I recently came across the PHP `array_intersect_uassoc()` function and I'm having a bit of trouble understanding how it works. I've read the documentation, but I'm still a bit confused. I was hoping someone here could help shed some light on it for me.
To provide some context, I'm currently working on a project where I need to compare two arrays and find the common elements based on their keys and values, but with a custom comparison function. I understand that `array_intersect_assoc()` can be used to find the common elements based on their values, but it doesn't allow for custom comparisons. This is where `array_intersect_uassoc()` comes in.
I've looked at the syntax and I understand that it takes in two or more arrays as arguments, and an optional callback function that compares the keys and values. However, I'm not entirely sure how to write the callback function and how it affects the comparison process.
It would be really helpful if someone could provide me with an example of using `array_intersect_uassoc()` with a custom callback function. I think having a real-world example would make it easier for me to understand and implement it in my project.
Thank you so much in advance for your help. I really appreciate it.
