What considerations should be taken into account when working with DateTime objects in PHP arrays?

When working with DateTime objects in PHP arrays, it's important to consider how to properly store and retrieve these objects without losing their date and time information. One common issue is that DateTime objects cannot be directly serialized or stored in arrays due to their complexity. To solve this, you can convert DateTime objects to strings using the `format()` method before storing them in arrays, and then recreate DateTime objects from these strings when retrieving them from arrays. 

// Storing DateTime objects in an array
$dateTime = new DateTime('2022-01-01 12:00:00');
$dateTimeString = $dateTime->format('Y-m-d H:i:s');
$array = ['date' => $dateTimeString];

// Retrieving DateTime objects from the array
$storedDateTimeString = $array['date'];
$storedDateTime = DateTime::createFromFormat('Y-m-d H:i:s', $storedDateTimeString);
