เปลี่ยนเป็น

<select id="ageSelect" onchange="updateValueY()">
  <?php for ($i = 0; $i <= 70; $i++) { ?>
    <option value="<?php echo $i; ?>" <?php if ($i === 0) { echo 'selected'; } ?>><?php echo $i; ?></option>
  <?php } ?>
</select>

The formula above uses a for loop to generate the options for the select element, iterating from 0 to 70. Each option has a value and label equal to the current iteration value, and if the current iteration value is 0, the selected attribute is added to the option.
