mgd_sort_group_id_array()

This function supports the mgd_group_id_array() function and provides the core sorting functionality. It is independent from the grouping code to ease debugging and make resorting easier.

Calling Syntax

function mgd_sort_group_id_array(&$array,
                                 $element_type, $group_type,
                                 $elementsortkey = "unsorted", 
                                 $groupsortkey = "unsorted",
                                 $elementsorting = SORT_REGULAR,
                                 $groupsorting = SORT_REGULAR )

Synopsis

Basically this function does the sorting for mgd_group_id_array(). The only difference is that it receives the Array by-reference and sorts it in place. All other parameters worke like in mgd_group_id_array().
