Getting unique values from 2 arrays

Question

I have 2 arrays that I\'m trying to get the unique values only from them. So I\'m not just trying to remove duplicates, I\'m actually trying to remove both duplicates.

Answer 1

Not to detract from Daniel Vandersluis's answer, but to add to it...

What you're looking for is basically an XOR operation of the arrays. To that end, "merlinyoda at dorproject dot net" provided the following routine, in a comment on http://php.net/manual/en/function.array-diff.php :

This function takes a different approach to calculating the XOR.
