[SOLVED] Finding elements that are in one array that are not in another

[tibberous]

I need to find all the elements that are in one array and not the other. I was able to do this with a foreach loop and the in_array function, but I was wondering if there isn't a more efficient way, since right now it is comparing an array of several thousand items to another array of several thousand items.

 

Thanks
