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

<?phpheader("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) );  */    //输出到浏览器    header("Pragma: public");    header("Expires: 0");    header("Cache-Control:must-revalidate, post-check=0, pre-check=0");    header("Content-Type:application/force-download");    header("Content-Type:application/vnd.ms-execl");    header("Content-Type:application/download");    header('Content-Type:application/octet-stream');    $encoded_filename = urlencode($filename);    $encoded_filename = str_replace("+", "%20", $encoded_filename);    $ua = $_SERVER["HTTP_USER_AGENT"];    if (preg_match("/MSIE/", $ua)) {      header('Content-Disposition: attachment; filename="' . $encoded_filename .
