Synopsis
array array_intersect_ukey(arrayarray1, arrayarray2[, ... arrayarrayN], callablefunction)
Returns an array consisting of every element in
array1 whose keys also exist in every other
array.
The function function is used to
compare the values of the elements for equality. The function is
called with two parameters—the keys to compare. It should return an
integer less than 0 if the first argument is less than the second, 0
if the first and second arguments are equal, and an integer greater
than 0 if the first argument is greater than the second.
