PHP를 사용하여 HTML 드롭다운 메뉴에서 옵션을 미리 선택하는 방법은 무엇입니까?

<select>
  <option value="January" selected="selected">January</option>
  <option value="February">February</option>
  <option value="March">March</option>
  <option value="April">April</option>
</select>

<?php $month = 'January'; ?>

<select>
  <option value="January" <?php if ($month == 'January') echo 'selected="selected"'; ?>>January</option>
  <option value="February">February</option>
  <option value="March">March</option>
  <option value="April">April</option>
</select>

$months = ['January', 'February', 'March', 'April'];
$selectedMonth = 'January';

echo '<select>';
foreach ($months as $value) {
  echo "<option value='$value'" . ($value == $selectedMonth ? ' selected="selected"' : '') . ">$value</option>";
}
echo '</select>';
