I have a threedimensional array in which I need to sort items in the first
dimension and items in the second dimension. The last items need to be
sorted according to a value of a key in the third dimension.

De basic structure of one of the items is (the second element in this case):
// this is the array $items_arr
1 = Array
1 > main_order = 2
1 > pages = Array
1 > pages > 0 = Array
1 > pages > 0 > page_order = 1
1 > pages > 1 = Array
1 > pages > 1 > page_order = 3
1 > pages > 2 = Array
1 > pages > 2 > page_order = 2

So I need to sort firstly on 'main_order', and after that I need to sort the
items within 'pages' according to 'page_order'. I've tried everything I can
think of, but cannot get it to work properly. This is what I have now:

// sorting the array by main item order --------------------> this works
perfect
foreach ($items_arr as $key => $row) {
$main_order[$key] = $row['main_order'];
}
array_multisort($main_order, SORT_ASC,SORT_NUMERIC, $items_arr);

// sorting the array of pages -----------------------------> this works but
throws a Warning: array_multisort() [function.array-multisort]: Array sizes
are inconsistent in ...
foreach($items_arr as $index => $arr){
foreach( $items_arr[$index]['pages'] as $pageindex => $page){
$page_order[$pageindex] = $page['page_order'];
}
array_multisort($page_order, SORT_ASC,SORT_NUMERIC,
$items_arr[$index]['pages']);
}

Anybody out there who can set me on the right track?

Thanks in advance,
John
