it seems to me that setReadDataOnly for the reader is breaking everything up with native office 2010 excel file.
I tried with a really simple excel file, reader on it, if i set the ReadDataOnly to true, the file isn't parsed because of this error:
Notice: Undefined offset: -1 in [...]PHPExcel\PHPExcel.php on line 191 Fatal error: Call to a member function getHighestRow() on a non-object in [myscript]
Removing the "setReadDataOnly", the file is parsed correctly.
Saving the file in excel 2003 format and parsing it, is working correctly even with ReadDataOnly to true.
Is there any problem with excel 2010 files? (i was sure excel 2010 and 2007 were the same..)
