How can PHP developers handle different date and time formats when working with database queries in PHP?

When working with database queries in PHP, PHP developers can handle different date and time formats by using the `DateTime` class to format dates before inserting them into the database or when retrieving dates from the database. This allows for consistency in date and time formats across different database operations.

// Example of formatting a date before inserting into the database
$date = new DateTime('2022-01-15');
$formattedDate = $date->format('Y-m-d');

// Example of formatting a date retrieved from the database
$rawDate = '2022-01-15';
$date = new DateTime($rawDate);
$formattedDate = $date->format('F j, Y');
