What are some best practices for sorting dates in PHP using mktime?

When sorting dates in PHP using mktime, it is important to convert the dates to timestamps before sorting them. This can be achieved by using the mktime function to create a timestamp for each date, and then sorting the timestamps in ascending or descending order as needed. 

// Sample array of dates
$dates = array("2023-10-15", "2023-10-10", "2023-10-20");

// Convert dates to timestamps using mktime
$timestamps = array_map(function($date) {
    list($year, $month, $day) = explode("-", $date);
    return mktime(0, 0, 0, $month, $day, $year);
}, $dates);

// Sort timestamps in ascending order
asort($timestamps);

// Display sorted dates
foreach($timestamps as $timestamp) {
    echo date("Y-m-d", $timestamp) . "\n";
}
