Can I read more files xls with the same instance?
require_once 'Excel/reader.php';

$dataxls = new Spreadsheet_Excel_Reader();

$dataxls->setOutputEncoding('CP1251');

$dataxls->read(file1.xls); // 3 rows
echo $dataxls->sheets[0]['numRows']; // print 3
for ($i = 2; $i <= $dataxls->sheets[0]['numRows']; $i++) {
      echo $dataxls->sheets[0]['cells'][$i][5]);
      echo ...
}
$dataxls->read(file2.xls); // 5 rows
echo $dataxls->sheets[0]['numRows']; // print 3
for ($i = 2; $i <= $dataxls->sheets[0]['numRows']; $i++) {
      echo $dataxls->sheets[0]['cells'][$i][5]);
      echo ...
}
