title: Read cells and preserve line breaks
body: <p>I have an excel file with line breaks inside the cells. I like to import the data into a database using phpspreadsheet.</p>
  
  <p>I have to split the line at the line break, as there are separate values for the database.</p>
  
  <p>It seems, that the retrieved cell value trims the line breaks.</p>
  
  <p>I use following code to import cells into rows.</p>
  
  <pre><code>        $rows = array();
          foreach ($sheetData-&gt;getRowIterator() as $row) {
              $cellIterator = $row-&gt;getCellIterator();
              $cellIterator-&gt;setIterateOnlyExistingCells(FALSE); 
              $cells = [];
              foreach ($cellIterator as $cell) {
                  $cells[] = $cell-&gt;getValue();
              }
             $rows[] = $cells;
          }
  </code></pre>
  
  <p>Is there a setting to preserve line breaks?</p>
