title: Extracting an embedded file from excel using Php on linux
body: <p>Hi and thanks for reading.</p>
  
  <p>I have an excel spreadsheet that has files inserted into 1 column, and I'm looking for a way to pull them out with php so that I can then copy them to another directory.</p>
  
  <p>So far I've had a look at PhpExcel and ExcelReader but unless I'm missing something, I cant see anywhere in the respective API's that details how to extract files. I have seen some code for getting hyperlinks and PHPExcel_Worksheet_Drawing and PHPExcel_Worksheet_MemoryDrawing, but nothing for general files.</p>
  
  <p>Does anyone know if this is possible, and if so using what utility class? Or even better, could someone please show me a sample piece of code.</p>
  
  <p>Thanks again for reading,
  Ian</p>
