You need to sort the array using php, not in codeigniter, and what you have is an object, read this http://stackoverflow.com/questions/4282413/php-sort-array-of-objects-by-object-fields — Emilio Gort, Sep 27 '13 at 19:38

Try this

 $yourarray = array(array(...), array(....),.....);

 function myFieldSort($a, $b)
 {
   return $b['created'] - $a['created'];
 }

 usort($yourarray, "myFieldSort");

function array_multi_subsort($array, $subkey)
{
    $b = array(); $c = array();

    foreach ($array as $k => $v)
    {
        $b[$k] = strtolower($v[$subkey]);
    }

    asort($b);
    foreach ($b as $key => $val)
    {
        $c[] = $array[$key];
    }

    return $c;
}

// sorting through "created" element in the arrays
$data = array_multi_subsort($array, 'created');
print_r($data);

Also reference on PHP.net manual:
http://php.net/manual/en/function.array-multisort.php

Please try this :

function array_multi_subsort($array, $subkey)
{
    $b = array(); $c = array();

    foreach ($array as $k => $v)
    {
        $b[$k] = strtolower($v->$subkey);
    }

    asort($b);
    foreach ($b as $key => $val)
    {
        $c[] = $array[$key];
    }

    return $c;
}

// sorting through "created" element in the arrays
$data = array_multi_subsort($array, 'created');
print_r($data);
