How can PHP be used to format a sequence of numbers into a specific date format?

To format a sequence of numbers into a specific date format using PHP, you can use the `date()` function along with `mktime()` or `strtotime()` to convert the numbers into a Unix timestamp. Then, you can use the `date()` function again with the desired date format to output the formatted date. 

$day = 15;
$month = 3;
$year = 2022;

$date = date('Y-m-d', mktime(0, 0, 0, $month, $day, $year));
echo $date;
