Can't read xls file.

```
I am setting up an automated procedure to read data from an xls file.
If I try to read it directly from the original file i get:

The filename asd.xls is not readable.

I've figured out that the condition that is leading to this error message is:

substr(this->data,0,8) != IDENTIFIER_OLE
(for the read method in the OLERead class) At around Line 115.

The thing is... if I open up the file in Excel and do a save as to a new file,
i am able to read that new file. Needless to say this doesn't work for an
automated process ;-). I don't know enough about excel, but I'm guessing the
version of the original file is too old, perhaps?

This is my code:

val(2,2);
?>

Any help/advice would be greatly appreciated !!

Start with excel_reader2.php and OLERead around line 115; reproduce the failure with the attached asd.xls and compare it with the file saved by Excel. Determine why the original file fails the IDENTIFIER_OLE check, then verify the reader handles it without requiring a manual Save As.
