Multi-dimension array sort by price Ascending and descending

This is the following array i am getting...! how could I sort it.

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [price] => 29.99
                    [params] => 
                    [text] => demotext
                )

            [1] => Array
                (
                    [price] => 22.40
                    [params] => 
                    [text] => demotext
                )

            [2] => Array
                (
                    [price] => 12.95
                    [params] => 
                    [text] => demotext
                )

            [3] => Array
                (
                    [price] => 9.60
                    [params] => 
                    [text] => demotext
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [price] => 8.16
                    [params] => 
                    [text] => demotext
                )

            [1] => Array
                (
                    [price] => 7.66
                    [params] => 
                    [text] => demotext
                )

            [2] => Array
                (
                    [price] => 7.19
                    [params] => 
                    [text] => demotext
                )

            [3] => Array
                (
                    [price] => 7.14
                    [params] => 
                    [text] => demotext
                )

        )

As you can see in index 2 array is not sorted beacuse 5.10 should on index [1] and 4.79 on index [2]

This what I sorted after great fuss , to break multi-dimension array into One Array and then sorted it according to price.

$array = your array;
// merging multi-dimension array into one array.
$result = array_merge_recursive($array[0],$array[1],$array[2],$array[3],$array[4]);
// now Sort array according to price
array_multisort($result, SORT_ASC);
foreach ($result as $key => $val) {
   foreach ($val as $new) { 
   }
echo  $new;
  }

Suppose $arr is your array then try:

foreach($arr as &$ar){
  foreach($ar as $key=>$r){
    $price[$key] = $r['price'];
    $params[$key] = $r['params'];
    $text[$key] = $r['text'];
  }
 array_multisort($price, SORT_DESC, $params, SORT_REGULAR, $text,SORT_REGULAR,$ar);
}

I think you could use array_multisort() for that http://ch2.php.net/array_multisort
