title: PHPExcel - Get date with forced format
body: <p>I use PHPexcel in a php application.
  I used <code>-&gt;getFormattedValue()</code> to get date from excel worksheet.</p>
  
  <p>When I use excel file A it gives me the following date format: <code>05/11/2016</code>
  But with the file B it gives following format :  <code>05-Nov-17</code></p>
  
  <p>How to force a date format in order to get a format like this  <code>05-Nov-17</code> all the time? How to convert it directly from <code>PHPExcel</code> to <code>PHP</code> date?</p>
