Natural sort an associative array?

Question

Given an array of arrays, how would I natural sort the inner arrays based on their values?

Example array:

array (size=2)
  0 => 
    array (size=1

PHP's usort() allows you to define a custom callback function for sorting:

usort($array, function($a, $b){
    if ($a['manager'] == $b['manager']) {
        return 0;
    }
    return ($a['manager'] < $b['manager']) ? -1 : 1;
});

For sorting months, you can use something like date('m', strtotime($a['month'])) to get the month number for comparison. More ways to do that can be found here: convert month from name to number
