title: Upload from any location not working with PHPExcel
body: <p>I am using PHPExcel plugin for reading excel and storing values in database.Its really cool and works very fine.But I have an issue when I am uploading an excel sheet from different location on my machine.<br/>
  I guess it is bcoz,the <strong>PHPExcel.php</strong> has a constant defined<br/></p>
  
  <pre><code>if (!defined('PHPEXCEL_ROOT')) {
     define('PHPEXCEL_ROOT', dirname(__FILE__) . '/');
     require(PHPEXCEL_ROOT .'PHPExcel/Autoloader.php');
  } 
  </code></pre>
  
  <p>I would like to know how can I upload and read file from any location?Also,I am not saving my file after uploading,but just reading and saving records to DB, as the purpose is to just enter the records into a database.How can I fix it? The <strong>documentation</strong> is really good and extensive but I am a bit short of time to explore it and also a newbie to Obj Oriented PHP<br/>
  Thanks for your time.</p>

  <strong>PS</strong> : I am not storing the file on the server,just reading and fetching the data from it.</p>
