How can PHP beginners effectively use the mktime function for date comparisons?

When using the mktime function in PHP for date comparisons, beginners should be aware that mktime returns a Unix timestamp, which is an integer representing the number of seconds since the Unix Epoch (January 1, 1970). To effectively compare dates using mktime, beginners can create timestamps for the dates they want to compare and then use simple comparison operators to determine which date is earlier or later. 

// Create timestamps for two dates
$date1 = mktime(0, 0, 0, 1, 1, 2022); // January 1, 2022
$date2 = mktime(0, 0, 0, 12, 31, 2021); // December 31, 2021

// Compare the two dates
if ($date1 > $date2) {
    echo "Date 1 is later than Date 2";
} elseif ($date1 < $date2) {
    echo "Date 1 is earlier than Date 2";
} else {
    echo "Date 1 is the same as Date 2";
}
