the right thing to do, for my opinion is to send your options data as JSON and to parse it with JS to required dropdown

for easy solution that will fit your situation, ill assume this is your PHP code:

//file name: do_dropdown.php
<?php
  $options = [1,2,3,4,5];
  echo '<select name="name">';
  foreach $options as $option{
     echo "<option value=$option>$option</option>";
  }
  echo '</select>';
?>

so you need to change your html file to PHP file (file.html -> file.php) and make sure you run on it PHP server (localhost as you are using right now)

<div id="result">
  <?php
    require_once "do_dropdown.php";
  ?>
</div>

there are much better solutions for this, but I guess your'e new in business so good luck :)

why don't you try this ? I think, It should not create any problem even if you're using HTML5. NOTE :: it should be .php extension file

    <html>
    <body>
            <?php
                    ....your code
                    ....from file <do_dropdown.php>
            ?>
    </body>
    </html>

you can also create a function and call it from here.
