View Full Version : array functions

08-31-2007, 11:56 AM
I've been going through the manual looking for a function but I can't find it but maybe someone here knows whether it exists and what it might be called.

I have 2 arrays, I want to reduce those arrays to a single array that only contains the values that exist in both arrays.

i cant think of one off the top of my head, but writing something like this would be simple enough.

Just loop one of them and for each value do an in_array() on the other one, if thats true then popultate a new one.

Other than that, in the 5 seconds i've looked, no idea.
