How can PHP date functions like date() and mktime() be utilized to create a dynamic date selection feature in a web application?

To create a dynamic date selection feature in a web application using PHP date functions like date() and mktime(), you can generate a dropdown menu for selecting days, months, and years. This can be achieved by using loops to populate the dropdown options with dynamically generated dates. 

<select name="day">
    <?php
    for ($i = 1; $i <= 31; $i++) {
        echo "<option value='$i'>$i</option>";
    }
    ?>
</select>

<select name="month">
    <?php
    for ($i = 1; $i <= 12; $i++) {
        $month = date('F', mktime(0, 0, 0, $i, 1));
        echo "<option value='$i'>$month</option>";
    }
    ?>
</select>

<select name="year">
    <?php
    $currentYear = date('Y');
    for ($i = $currentYear; $i >= $currentYear - 100; $i--) {
        echo "<option value='$i'>$i</option>";
    }
    ?>
</select>
