Is it necessary to convert dates to timestamps in order to properly sort them in PHP?

To properly sort dates in PHP, it is not necessary to convert them to timestamps. You can use the `strtotime()` function to convert the dates to Unix timestamps, which can then be easily compared and sorted. This allows you to sort dates in ascending or descending order without needing to manually convert them to timestamps. 

$dates = ['2022-01-15', '2022-02-10', '2021-12-25'];

usort($dates, function($a, $b) {
    return strtotime($a) - strtotime($b);
});

print_r($dates);
