ThinkPHP框架实现导出excel数据的方法示例【基于PHPExcel】

<"Content-type: text/html; charset=utf-8");
class MesTestAction extends Action {
  //测试导出excel数据
  public function tpGetExcel() {
    //创建对象
    import("ORG.Util.PHPExcel"); //从PHPExcel目录导PHPExcel.php类文件
    $excel = new PHPExcel();
    $data = M()->query('SELECT userid,username,stepgoal FROM tp_data_user LIMIT 2775');
    //Excel表格式,这里简略写了3列
    $letter = array('A','B','C');
    //表头数组
    $tableheader = array('userid','用户名','目标步数');
    $count= count($data);//总的数据行数
    $listNum = 500;//每个sheet页最大数据行数
    $num = ceil($count/$listNum);//sheet页个数
    $MuitData = array_chunk($data,$listNum,false);//分割总的数据，每页最多$listNum行有效数据
  //var_dump($MuitData);//die('as');
  //缺省情况下,PHPExcel会自动创建第一个SHEET,其索引SheetIndex=0
  //设置 当前处于活动状态的SHEET 为PHPExcel自动创建的第一个SHEET
  $excel->setActiveSheetIndex(0); //objPHPExcel
  //设置sheet的title
  $excel->getActiveSheet()->setTitle('考核得分第'.'1'.'页');
  //设置sheet的列名称
    for($k = 0; $k < count($tableheader); ++$k) {
      $excel->getActiveSheet()->setCellValue("$letter[$k]".'1',"$tableheader[$k]");//第一行数据
    }
  //填充表格信息 处理第1块数据
  $crrntSheetLineNo = count($MuitData[0]) + 1;
  for ( $j = 2; $j <= $crrntSheetLineNo; ++$j) { //遍历每一行
    $k = 0;
    foreach ( $MuitData[0][$j - 2] as $key => $value ) {//遍历具体行的某一列
      $excel->getActiveSheet()->setCellValue("$letter[$k]".$j,"$value");//第$k列 第$j行
      $k++;
    }
  }
  //后续的sheet页及数据块
    for ( $i = 1; $i <$num; ++$i) {
      //创建第$i个sheet
      $msgWorkSheet = new PHPExcel_Worksheet($excel, '考核得分第'.($i + 1).'页'); //创建一个工作表
      $excel->addSheet($msgWorkSheet); //插入工作表
      $excel->setActiveSheetIndex($i); //切换到新创建的工作表
      //设置sheet的列名称
      for($k = 0; $k < count($tableheader); ++$k) {
        $excel->getActiveSheet()->setCellValue("$letter[$k]1","$tableheader[$k]");//第一行数据
      }
      //填充表格信息 处理第$i块数据
    $crrntSheetLineNo = count($MuitData[$i]) + 1; //var_dump($crrntSheetLineNo);var_dump($MuitData[$i-1]);die('as');
      for ( $j = 2; $j <= $crrntSheetLineNo; ++$j) { //遍历每一行
        $k = 0;
        foreach ( $MuitData[$i-1][$j - 2] as $key => $value ) {//遍历具体行的某一列
          $excel->getActiveSheet()->setCellValue("$letter[$k]$j","$value");//第$k列 第$j行
          ++$k;
        }
      }
      usleep(100);
    }
    //创建Excel输出对象
    $filename = "大奖赛培训考核得分.xls";
    $write = new PHPExcel_Writer_Excel5($excel);
    ob_end_clean();//清除缓冲区,避免乱码
  /*
  //输出到本地
    $write->save( iconv('utf-8', 'gbk', $filename) );
