What improvement does the second code snippet offer in terms of selecting the date value?

The second code snippet improves the selection of the date value by using the `date_create` function to create a DateTime object from the string date value. This ensures that the date value is correctly parsed and formatted, making it easier to work with and manipulate in PHP.

// Original code snippet
$date = $_POST['date'];
$timestamp = strtotime($date);
$formatted_date = date('Y-m-d', $timestamp);

// Improved code snippet
$date = $_POST['date'];
$date_obj = date_create($date);
$formatted_date = date_format($date_obj, 'Y-m-d');
