What are some tips for avoiding errors or misunderstandings when working with date comparisons in PHP?

When working with date comparisons in PHP, it is important to ensure that the dates are in the correct format and timezone to avoid errors or misunderstandings. One way to do this is to use the DateTime class to create date objects and compare them using the appropriate methods like `diff()` or `format()`. 

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-15');

// Compare dates
if ($date1 < $date2) {
    echo "Date 1 is before Date 2";
} elseif ($date1 > $date2) {
    echo "Date 1 is after Date 2";
} else {
    echo "Date 1 is equal to Date 2";
}
