What are the best practices for handling date formats and conversions in PHP when comparing dates?

When comparing dates in PHP, it's important to ensure that the dates are in the same format to get accurate results. One way to handle date formats and conversions is to use the DateTime class to standardize the dates before comparing them. This allows for easy comparison and manipulation of dates in a consistent manner. 

$date1 = '2022-01-15';
$date2 = '15/01/2022';

$dateObj1 = DateTime::createFromFormat('Y-m-d', $date1);
$dateObj2 = DateTime::createFromFormat('d/m/Y', $date2);

if ($dateObj1 < $dateObj2) {
    echo 'Date 1 is before Date 2';
} elseif ($dateObj1 > $dateObj2) {
    echo 'Date 1 is after Date 2';
} else {
    echo 'Date 1 is the same as Date 2';
}
