  <para>
   Computes the intersection of arrays with additional index check, compares
   data and indexes by a callback functions Note that the keys are used in
   the comparison unlike in <function>array_uintersect</function>.
   Both the data and the indexes are compared by using separate callback functions.

       For comparison is used the user supplied callback function.
       It must return an integer less than, equal
       to, or greater than zero if the first argument is considered to
       be respectively less than, equal to, or greater than the
       second.
