In what situations would using relative expressions in PHP be advantageous when working with date calculations for generating select lists?

When working with date calculations in PHP to generate select lists, using relative expressions can be advantageous when you need to dynamically generate date ranges based on the current date. This allows for flexibility in generating options such as "next 7 days" or "previous month", without needing to manually calculate specific dates. 

<select name="date_range">
    <?php
    for ($i = 0; $i < 7; $i++) {
        $date = strtotime("+" . $i . " days");
        echo "<option value='" . date("Y-m-d", $date) . "'>" . date("Y-m-d", $date) . "</option>";
    }
    ?>
</select>
