title: Remove empty rows in PHPexcel
body: <p>I have the following code . </p>
  
  <pre><code>$sheet = $objPHPExcel-&gt;getSheet(0); 
  $highestRow = $sheet-&gt;getHighestDataRow(); 
  $highestColumn = $sheet-&gt;getHighestDataColumn();
  for ($row = 2; $row &lt;= $highestRow; $row++){ 
      $rowData = $sheet-&gt;rangeToArray('A' . $row . ':' . $highestColumn . 
         $row,NULL,TRUE,FALSE);
  
  }
  </code></pre>
  
  <p>I need to ignore rows if all columns are empty.I have seen links <a href="https://stackoverflow.com/questions/12285511/ignore-empty-cells-phpexcel">ignore empty columns</a> ,but am not sure about this will work for me. I dont need to eliminate columns if it is empty,but I need to eliminate entire row,if all the columns are empty.</p>
