title: How to leave blank columns in a CSV file
body: <p>I have a script that stores results of a form to a CSV file on the server.</p>
  
  <p>I have to make another form doing the same thing but instead of filling all the columns in the CSV file, I only need to fill in few selected and leave the rest as blank.</p>
  
  <p>Currently, this is what I am using to write to my CSV:</p>
  
  <pre><code>$data = "$Name" . ',' . "$Address" . ',' . "$Email" . ',' . "$Cell_Phone". ',' . "$selected". $cr;
  </code></pre>
  
  <p>How can I now leave the $cell_phone and <code>$selected</code> columns as blank?</p>
