What potential pitfalls should PHP developers be aware of when using strtotime() to add a month to a date?

When using strtotime() to add a month to a date in PHP, developers should be aware that it does not always handle edge cases, such as adding a month to the end of a month with fewer days. To solve this issue, developers can use the DateTime class along with DateInterval to accurately add a month to a date. 

$date = new DateTime('2022-01-31');
$date->add(new DateInterval('P1M'));
echo $date->format('Y-m-d'); // Output: 2022-02-28
