Sort Multi Array in PHP

Question

Does anybody have an idea how can I sort this array by key (date) in PHP?

Array
(   
    [2011-02-16] => Array
        (
            [date] => 2011-02-16

Well, as sorting on the key would do it, ksort() would work for you!

But if you really want to sort on the date element, you would use uasort() with a sort function like this

  function compare($a, $b)
  {
      if ($a['date']==$b['date']) return 0;
      return ($a['date']>$b['date'])?1:-1;
  }

  uasort($myarray, 'compare');
