What are the advantages and disadvantages of using automated solutions versus manual adjustments for date validations in PHP?

When validating dates in PHP, automated solutions like the `DateTime` class can provide more robust and reliable validation compared to manual adjustments. Automated solutions handle edge cases and leap years automatically, reducing the likelihood of errors. However, manual adjustments can offer more flexibility and customization in certain scenarios. 

// Automated solution using DateTime class
$dateString = '2022-02-30';
$date = DateTime::createFromFormat('Y-m-d', $dateString);
if ($date && $date->format('Y-m-d') === $dateString) {
    echo 'Valid date';
} else {
    echo 'Invalid date';
}
