I have a question about the PHP array_uintersect() function. I've been trying to understand how it works, but I'm having some trouble. Could someone please explain it to me and provide an example?
I've looked through the PHP documentation, but I'm still not entirely clear on how this function works. I understand that array_uintersect() is used to compute the intersection of arrays using a callback function for the comparison of values. However, I'm not sure how exactly this callback function should be implemented or what it should return.
It would be really helpful if someone could provide a simple and clear example of how to use the array_uintersect() function. This would help me better understand how the callback function should be structured and how the overall function works.
Whether you can explain it in your own words or link to a reliable resource that explains it well, any help would be greatly appreciated. Thanks in advance!
