          filter_array() returns an array holding the items of <arr>
          which passed sucessfully through the function <fun> found in
          object <ob>.  The function <fun> is called for each element
          in <arr> with that element as parameter.  The second
          parameter <extra> and following parameters are sent in each
          call if given.  An object is considered to have passed
          sucessfully through <fun> (and hence is included in the
          return array) if <fun> returns 1.  If f is passed it is used
          instead of ob->fun().  If <arr> is not an array, then 0 will
          be returned.
