Are there built-in PHP functions that can accurately add a specified number of months to a given date without manual adjustments?

To accurately add a specified number of months to a given date in PHP without manual adjustments, you can use the `DateTime` class along with the `DateInterval` class. By creating a `DateTime` object with the initial date and then adding the specified number of months using a `DateInterval` object, you can achieve the desired result without needing to handle edge cases like varying month lengths. 

$initialDate = new DateTime('2022-01-15');
$monthsToAdd = 3;

$modifiedDate = $initialDate->add(new DateInterval('P' . $monthsToAdd . 'M'));

echo $modifiedDate->format('Y-m-d'); // Output: 2022-04-15
