title: Make first option value null in select menu coming from MySQL database
body: <p>I am dumping some results from the database directly into  tag in the html, how I can make the first option value to be null, and after that the database results to be sorted? This way I will have this drop down menu an option to not choose anything from it.  </p>
  
  <p>this is my code here: </p>
  
  <pre><code>&lt;?php 
      $select = new Users;
      $stmt = $select-&gt;selecttema();
      while( $row = $stmt-&gt;fetch()){ 
          echo '&lt;option value="' . $row['id'] . '"&gt;' . $row['topic'] . '&lt;/option&gt;';
      } 
  ?&gt;
  </code></pre>
