title: Reading xlsx file in PHP
body: <p>I'm following <a href="http://matthom.com/archive/2010/04/14/read-microsoft-office-2007-files-with-php" rel="noreferrer">this tutorial</a> to read the <code>xlsx</code> file format.  I'm reading xlsx file. Working fine. But it display all the file content in one line. How to add space between them? Thanks
  Here is my code.</p>
  
  <pre><code>    $file_upload = 'book.zip';
  $zip = new ZipArchive;
  // the string variable that will hold the file content
  $file_content = " ";
  // the uploaded file
  //$file_upload = $file -&gt; upload["tmp_name"];
  if ($zip -&gt; open($file_upload) === true) {
    // loop through all slide#.xml files
    if ( ($index = $zip -&gt; locateName("xl/sharedStrings.xml")) !== false ) {
                      $data = $zip -&gt; getFromIndex($index);
  
                      $xml = DOMDocument::loadXML($data, LIBXML_NOENT | LIBXML_XINCLUDE | LIBXML_NOERROR | LIBXML_NOWARNING);
  
                      $file_content = strip_tags($xml -&gt; saveXML());
                }
  echo $file_content;
  }
  </code></pre>
