title: PHPExcel cannot open a file
body: <p>I'm trying to open an xlsx file, modify it and save it with another name. It's supposed to be quite simple but he doesn't work. </p>
  
  <p>The file is 292 Ko , empty file with only 1 cell</p>
  
  <p>Here is my code :</p>
  
  <pre><code>&lt;?php
  error_reporting(E_ALL);
  date_default_timezone_set('Europe/London');
  set_include_path('./lib/PHPExcel/Classes/');
  require_once('PHPExcel/IOFactory.php');
  
  ini_set('memory_limit','128M');
  
  $toModifyPath = "./toModify.xlsx";
  $outPath = "./out.xlsx";
  $fileType = "Excel2007";
  
  
  echo '&lt;p&gt;Starting...&lt;/p&gt;';
  
  
  
  //Open
  $objReader = PHPExcel_IOFactory::createReader($fileType);
  $objPHPExcel = $objReader-&gt;load($toModifyPath) //&lt;-- THIS LINE IS BLOCKING WITH NO ERROR
  echo '&lt;p&gt;Opened&lt;/p&gt;';
  
  
  //Starting from here, it's working
  
  //Modify
  $objPHPExcel-&gt;setActiveSheetIndex(0);
  $objPHPExcel-&gt;getActiveSheet()-&gt;setCellValue('C6', '4')-&gt;setCellValue('C7', '5')-&gt;setCellValue('C8', '6')-&gt;setCellValue('C9', '7');
  echo '&lt;p&gt;Modifed&lt;/p&gt;';
  
  //Save
  $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, $fileType);
  $objWriter-&gt;save($outPath);
  echo '&lt;p&gt;Saved&lt;/p&gt;';
  
  echo '&lt;p&gt;Done !&lt;/p&gt;';
  
  ?&gt;
  </code></pre>
  
  <p>The output is "Starting..." So the line <code>$objPHPExcel = $objReader-&gt;load($toModifyPath)</code> is blocking with no error and i dont understand why. Anyone gots a clue ?</p>
  
  <p>PHP Version 5.2.3
  PHPExcel 1.8</p>
