        $strClass = 'Error';
    }
}

A file upload is a file upload. Doesn't matter if it's .txt, .jpg, .exe, or .foobarbaz. PHP doesn't care.

What you ARE doing wrong is making up a totally fake name for that file and somehow expecting PHP to magically fix that.

You need to first confirm that an upload actually occurred and SUCCEEDED

if ($_FILES['frmUpload']['error'] !== UPLOAD_ERR_OK) {
   die("File upload failed with error code #" . $_FILES['frmUpload']['error']);
}

Then just use the standard temp filename that PHP assigns, not the utterly meaning filename that existed on the client:

$data->read($_FILES['frmUpload']['tmp_name']);

And of course, you should probably check if that upload really is an excel file, and not something completely different.
