phpexcel导入导出excel，并解决超出26列出现的错误

Thinkphp

$lists = '';             //sql查询结果;

$this->exportExcel($filename,$title,$headArr,$order_listss,$total_name,$total_money);

YII
一 ：导入excel文件
引入phpexcel类库
require(Yii::getAlias('@common').'/library/PHPExcel/PHPExcel.PHP');
//这是yii的引入方式 根据情况自己引入类库

1.要上传文件
if (!empty ( $_FILES ['excel'] ['name'] )){

    $tmp_file = $_FILES ['excel'] ['tmp_name'];

     $file_types = explode ( ".", $_FILES ['excel'] ['name'] );

    $file_type = end($file_types);

  /*判别是不是.xls文件，判别是不是excel文件*/

  if ((strtolower ($file_type) != "xls")  && (strtolower ($file_type) != "xlsx")&& (strtolower ($file_type) != "csv")){

      $error ="文件类型不对";

     die;

  }

//DS 是自己定义的/ 和在Linux里是\
  需要自己定义
  $dir=date("Y-m-d",time());

  if(!is_dir(ROOT_PATH.DS."upload".DS."excel".DS.$dir)){

  

    mkdir(ROOT_PATH.DS."upload".DS."excel".DS.$dir);

  }

  //注意，如果upload前加 / 则报错。

  $path = 'upload'.DS.'excel'.DS.$dir.DS. time().rand(1000,9999) . '.' . $file_type;

  $pic_name = time() . rand(10000, 99999) . "." . $file_type;//图片名称

if (!move_uploaded_file($tmp_file, $path)) { //临时文件转移到目标文件夹

    $error ="上传失败";

     return $this->redirect(['index', 

                'error' => $error,

            ]);

     die;

}
2.读取上传的文件
  //加载导入类

  $PHPExcel=new \PHPExcel();

  $PHPReader = new \PHPExcel_Reader_Excel2007();

  if(!$PHPReader->canRead($path)){

    $PHPReader = new \PHPExcel_Reader_Excel5();

    if(!$PHPReader->canRead($path)){

       return false;

     }

  }

  $PHPExcel=$PHPReader->load($path);//载入文件

  // print_r($PHPExcel);die;

  $currentSheet=$PHPExcel->getSheet(0); //获取表中的第一个工作表，如果要获取第二个，把0改为1，依次类推

  $allColumn=$currentSheet->getHighestColumn();//获取总列数d

++$allColumn;

  $allRow=$currentSheet->getHighestRow();//获取总行数

  

// echo $allRow;die;

  // print_r($allRow);die;

  $arr=array();

  for($currentRow = 3;$currentRow <= $allRow;$currentRow++){

      /**从第A列开始输出*/

      $i=0;

      for($currentColumn = 'A'; $currentColumn !=$allColumn; $currentColumn++){ //大于26列

         if($i>25){

          $num =ord($currentColumn)+$i;

         }else{

            $num =ord($currentColumn);

         }

        // echo $i.$currentColumn; echo "<br>";

        $val = $currentSheet->getCellByColumnAndRow($num - 65,$currentRow)->getValue(); /*ord()将字符转为十进制数*/

        

         

          /**如果输出汉字有乱码，则需将输出内容用iconv函数进行编码转换，如下将gb2312编码转为utf-8编码输出*/

          // $arr[$currentRow][]=  iconv('utf-8','gb2312', $val)."＼t";

          $arr[$currentRow][]=  trim($val);

          $i++;

      }

  }

  //删除全部为空的行

  foreach ($arr as $key=>$vals){

      $tmp = '';

      foreach($vals as $v){

          $tmp .= $v;

      }

      if(!$tmp) unset($arr[$key]);

  }

       print_r($arr);die;

二：导出excel
public function getExcel($fileName,$headArr,$data){

//$headArr, 设置的表头

//$data 传过来的需要导出的数据 二维数组
        $date = date("Y_m_d",time());

        $fileName .= "_{$date}.xls";

        //创建PHPExcel对象，注意，不能少了\

        $objPHPExcel = new \PHPExcel();

        $objProps = $objPHPExcel->getProperties();

        //设置表头 超过26列

        $key = 0;

        foreach($headArr as $v){

            //注意，不能少了。将列数字转换为字母\

            $colum = \PHPExcel_Cell::stringFromColumnIndex($key);

            $objPHPExcel->setActiveSheetIndex(0) ->setCellValue($colum.'1', $v);

            $key += 1;

        }

        //设置表头

       /* $key = ord("A");

        //print_r($headArr);exit;

        foreach($headArr as $v){

            $colum = chr($key);

            $objPHPExcel->setActiveSheetIndex(0) ->setCellValue($colum.'1', $v);

            $objPHPExcel->setActiveSheetIndex(0) ->setCellValue($colum.'1', $v);

            $key += 1;

        }*/

        $column = 2; //从第二行写入数据 第一行是表头

        $objActSheet = $objPHPExcel->getActiveSheet();

        //print_r($data);exit;

        /*foreach($data as $key => $rows){ //行写入

            $span = ord("A");

            foreach($rows as $keyName=>$value){// 列写入

                $j = chr($span);

                $objActSheet->setCellValue($j.$column, $value);

                $span++;

            }

            $column++;

        }*/
此处解决列超出26的问题
        foreach($data as $key => $rows){ //行写入
            $span = 0;
            foreach($rows as $keyName=>$value){// 列写入
                $j = \PHPExcel_Cell::stringFromColumnIndex($span);
                $objActSheet->setCellValue($j.$column, $value);
                $span++;
            }
            $column++;
        }

        $fileName = iconv("utf-8", "gb2312", $fileName);

       /*  //重命名表
        $objPHPExcel->getActiveSheet()->setTitle($date);
        //设置字体大小
        $objPHPExcel->getDefaultStyle()->getFont()->setSize(14);
        //设置单元格宽度
        $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(15);
        //设置默认行高
        $objPHPExcel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(23);
*/
        
        //重命名表
        //$objPHPExcel->getActiveSheet()->setTitle('test');
        //设置活动单指数到第一个表,所以Excel打开这是第一个表
        $objPHPExcel->setActiveSheetIndex(0);
        ob_end_clean();//清除缓冲区,避免乱码
        header('Content-Type: application/vnd.ms-excel');
        header("Content-Disposition: attachment;filename=\"$fileName\"");
        header('Cache-Control: max-age=0');
        $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
        $objWriter->save('php://output');
//文件通过浏览器下载
        exit;
