How can the strtotime function be utilized to adjust dates in PHP scripts?

The strtotime function in PHP can be used to adjust dates by converting textual date descriptions into Unix timestamps. This allows for easy manipulation of dates by adding or subtracting seconds, minutes, hours, days, weeks, months, or years to a given date. By using strtotime, you can easily adjust dates in PHP scripts without having to manually calculate date differences.

// Adjusting a date by adding 1 week
$date = "2022-01-01";
$new_date = date("Y-m-d", strtotime($date . " +1 week"));
echo $new_date;
