Close... I think array keys are preserved from the (original) first
array, but other than that those appear to be the values that should
intersect.

After a var_dump I am seeing that there is an extra space in each
element of one array, so no intersection occurs.
Well then there you have it... having an extra space means that the
strings in the first array won't match the strings in the second array.
Perhaps you can array_intersect(array_walk($array1, 'trim'), $array2)
