title: Loading Excel file with PHPExcel
body: <p>I have following code:</p>
  <pre><code>public function actionSearch()
  {
      $inputFileName = &quot;C:/Apache2/htdocs/filePurchase/files/file.xlsx&quot;;
      $objReader = new PHPExcel_Reader_Excel2007();
      $objPHPExcel = $objReader-&gt;load($inputFileName);
  }
  </code></pre>
  <p>When i run this action on browser, this message raised:</p>
  <blockquote>
  <p>The connection was reset</p>
  <p>The connection to the server was reset while the page was loading.</p>
  </blockquote>
  <p>With following code is no problem:</p>
  <pre><code>$inputFileName = &quot;C:/Apache2/htdocs/filePurchase/files/file.xlsx&quot;;
  $objPHPExcel = PHPExcel_IOFactory::load($inputFileName);
  </code></pre>
  <p>What's the problem?</p>
  <hr />

  <p><strong>var_dump($objReader):</strong></p>
