What are common pitfalls when using the date() function in PHP for comparisons?

Common pitfalls when using the date() function for comparisons in PHP include not considering timezones, not using the correct date format, and not accounting for daylight saving time changes. To avoid these issues, it's recommended to use the DateTime class along with the DateTimeZone class to handle timezones properly and ensure accurate date comparisons. 

$date1 = new DateTime('2022-01-01', new DateTimeZone('UTC'));
$date2 = new DateTime('2022-01-01', new DateTimeZone('UTC'));

if ($date1 == $date2) {
    echo 'Dates are equal';
} else {
    echo 'Dates are not equal';
}
