我目前拥有的代码：

<?PHP
  /** PHPExcel */
  require_once '../Classes/PHPExcel.PHP';
  /** PHPExcel_IOFactory */
  require_once '../Classes/PHPExcel/IOFactory.PHP';
  // Create new PHPExcel object
  $objPHPExcel = new PHPExcel();
  // Set properties
  $objPHPExcel->getProperties()->setCreator("Maarten Balliauw")
                               ->setLastModifiedBy("Maarten Balliauw")
                               ->setTitle("Office 2007 XLSX Test Document")
                               ->setSubject("Office 2007 XLSX Test Document")
                               ->setDescription("Test document for Office 2007 XLSX,generated using PHP classes.")
                               ->setKeywords("office 2007 openxml PHP")
                               ->setCategory("Test result file");
  $result = 'select * from table1';
  for($i=0;$i<count($result);$i++) {
    $result1 = 'select * from table2 where table1_id = ' . $result[$i]['table1_id'];
    for ($j=0;$j<count($result1);$j++) {
      $objPHPExcel->setActiveSheetIndex(0)->setCellValue('A' . $j,$result1[$j]['name']);
    }
    // Set active sheet index to the first sheet,so Excel opens this as the first sheet
    $objPHPExcel->setActiveSheetIndex(0);
    // Save Excel 2007 file
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
    $objWriter->save(str_replace('.PHP','.xlsx',__FILE__));
    // Echo done
    echo date('H:i:s') . " Done writing file.\r\n";       
  }
?>

上面的代码执行并将n个.xlsx文件保存在该文件夹中,但是我遇到的问题是在所有保存的excel文件中执行的for循环中最大的count(result1).
