How can PHP be used to pass values from dropdown menus to another page using POST method?

To pass values from dropdown menus to another page using the POST method in PHP, you can use a form with a dropdown menu and submit button. When the form is submitted, the selected value from the dropdown menu will be sent to the next page as a POST parameter. On the receiving page, you can access the selected value using the $_POST superglobal. 

<!-- HTML form with dropdown menu -->
<form action="next_page.php" method="post">
  <select name="dropdown">
    <option value="value1">Option 1</option>
    <option value="value2">Option 2</option>
    <option value="value3">Option 3</option>
  </select>
  <input type="submit" value="Submit">
</form>
```

```php
// next_page.php
if(isset($_POST['dropdown'])) {
  $selected_value = $_POST['dropdown'];
  echo "Selected value: " . $selected_value;
} else {
  echo "No value selected";
}
