Spreadsheet_Excel_Writer data output is damaged

Question

I use Spreadsheet_Excel_Writer to generate .xls file and it works fine until I have to deal with a large amount of data. On certain stage it just writes some nonsense chars and quits filling certain columns. However some columns are field up to the end (generally numeric data)

I'm not quite sure how the xls document is formed: row by row, or col by col... Also it is obviously not an error in a string, because when i cut out some data, the error appears a little bit further.

I think there is no need in all of my code

here are some essentials

$filename = 'file.xls';
$workbook = & new Spreadsheet_Excel_Writer(); 
$workbook->setVersion(8); 
$contents =& $workbook->addWorksheet('Logistics');
$contents->setInputEncoding('UTF-8');

$workbook->send($filename);

//here is the part where I write data down
$contents->write(0, 0, 'Field A');
$contents->write(0, 1, 'Field B');
$contents->write(0, 2, 'Field C');

$ROW=1;
foreach($ordersArr as $key=>$val){
  $contents->write($ROW, 0, $val['a']);
  $contents->write($ROW, 1, $val['b']);
  $contents->write($ROW, 2, $val['c']);

  $ROW++;
}
$workbook->close();

I had the same problem, I found this solution that works for me:

The solution is change in Root.php \ line 623 :

fwrite($FILE, pack("V", 1));

to

fwrite($FILE, pack("V", $num_sb_blocks));

the file is pear/OLE/PPS/Root.php in package OLE 1.0.0RC2 (beta)
