修改多维数组中的键值

Question

How can I properly format or update a date_created value inside an array so after I will have the same array but with some modified values in it ?

I want to format a date_created values with this function date("D, d FY, H:i:s", strtotime($date_created));

Here is the result of dumped array - var_dump($query) :

array
  0 => 
    array
      'id' => string '2' (length=1)
      'title' => string 'Title 2' (length=55)
      'date_created' => string '2011-03-09 08:04:14' (length=19)
  1 => 
    array
      'id' => string '1' (length=1)
      'title' => string 'Title 2' (length=57)
      'date_created' => string '2011-08-14 18:34:04' (length=19)

All you'll have to do is iterate over the array, change the values and replace the sub array with the original in the same index.

foreach($query as $key => $subArray){
  $subArray['date_created'] = date("D, d F Y, H:i:s", strtotime($subArray['date_created']));
  $query[$key] = $subArray['date_created'];
}
