How can one compare multiple dates in PHP to determine the most recent one?

To compare multiple dates in PHP to determine the most recent one, you can convert the dates to Unix timestamps using the strtotime() function, then compare the timestamps to find the highest value, which corresponds to the most recent date. 

$dates = ["2022-01-15", "2022-02-20", "2022-03-10"];

$latest_date = $dates[0];
foreach ($dates as $date) {
    if (strtotime($date) > strtotime($latest_date)) {
        $latest_date = $date;
    }
}

echo "The most recent date is: " . $latest_date;
