Attempting to use an .xls file from $_FILE

```
1. Upload an xls file using a Zend file element
2. Grab the file via $_FILE
3. Create a Spreadsheet Excel Reader object

There are no errors and the page executes property, however there is no data in
the new object.

I've checked the upload process itself, and I'm able to work with a csv file
(without using php-excel-reader).

Any suggestions? Is it possible to use php-excel-reader with an uploaded file?

Start by reproducing the reported sequence: upload an .xls file through a Zend file element, read it from $_FILE, and create a Spreadsheet Excel Reader object. Compare this with the working CSV upload and verify whether the uploaded workbook data becomes available; done means the cause and a working path, or a confirmed limitation, are documented.
