    $result = array();
    $objReader = PHPExcel_IOFactory::createReader('Excel5');
    if(!$objReader->canRead($filename)){
        $objReader = PHPExcel_IOFactory::createReader('Excel2007');
        if(!$objReader->canRead($filename)){
            echo 'no Excel';
            return;
        }
    }
    $objReader->setReadDataOnly(true);
    $objPHPExcel = $objReader->load($filename);
    $AllSheets = $objReader->load($filename);
    $AllSheet = $AllSheets->getAllSheets();
    foreach ($AllSheet as $sheet) {
        $result[$sheet->getTitle()] = $sheet->toArray();
    }
    return $result;
