What are the advantages and disadvantages of using the array_filter function in PHP for date comparisons?

When comparing dates in PHP, using the array_filter function can be advantageous as it allows for filtering an array based on a specified callback function, which can be useful for comparing dates. However, one disadvantage is that the callback function may need to be carefully constructed to accurately compare dates, as PHP's date comparison can sometimes be tricky due to different date formats and timezones. 

// Example code snippet using array_filter to compare dates
$dates = ['2022-01-01', '2022-02-01', '2022-03-01', '2022-04-01'];

$filteredDates = array_filter($dates, function($date) {
    $today = date('Y-m-d');
    return strtotime($date) > strtotime($today);
});

print_r($filteredDates);
