sorting array in predefined order - uksort

I am trying to sort array by key to a defined order - I thought uksort would be best option. Here's what i have come up with from the manual example - however it doesn't work at all. I want to sort this array by $region Array looks like this: $articles[$region][$article_id][$column_name] // END ADD ARTICLES TO MULTIDIMENSIONAL ARRAY // SORT ARRAY BY REGION function cmp ($a, $b) { if ($a == 'national') return 0; elseif ($a == 'international') return 5; elseif ($a == 'west') return 1; elseif ($a == 'south') return 2; elseif ($a == 'east') return 3; elseif ($a == 'midwest') return 4; } uksort ($articles, "cmp"); Thanks much, olinux __________________________________________________ Do You Yahoo!?
