I am currently creating a sorting method that consists of values from an mysql query.

Here\'s a brief view of the array:

        [0]

Finally found this wonderful function at PHP.net:

        function array_msort($array, $cols)
        {
            $colarr = array();
            foreach ($cols as $col => $order) {
                $colarr[$col] = array();
                foreach ($array as $k => $row) { $colarr[$col]['_'.$k] = strtolower($row[$col]); }
            }
            $eval = 'array_multisort(';
            foreach ($cols as $col => $order) {
                $eval .= '$colarr[\''.$col.'\'],'.$order.',';
            }
            $eval = substr($eval,0,-1).');';
            eval($eval);
            $ret = array();
            foreach ($colarr as $col => $arr) {
                foreach ($arr as $k => $v) {
                    $k = substr($k,1);
                    if (!isset($ret[$k])) $ret[$k] = $array[$k];
                    $ret[$k][$col] = $array[$k][$col];
                }
            }
            return $ret;

        }

This is how each country looks like: $array['countries'] = in_array($needle, $haystack); }

$array = $array = array_msort($array, array('countries'=>SORT_DESC, 'id'=>SORT_ASC));

Thanks all for your help!
