thinkphp5.1 框架导入/导出excel文件操作示例

本文实例讲述了thinkphp5.1 框架导入/导出excel文件操作。分享给大家供大家参考，具体如下：

thinkphp5.1 导入excel文件

public function importexcel()
  {
    try {
      //获取表格的大小，限制上传表格的大小
      if ($_files['file']['size'] > 10 * 1024 * 1024) { //文件过大
        log_debug($log_title . 'end === msg：' . '文件过大');
        parent::endback(['state' => 0, 'msg' => '文件过大']);
      }
 
      //限制上传表格类型
      $ext = substr(strrchr($_files['file']["name"], '.'), 1);
      if ($ext != 'xls' && $ext != 'xlsx') {
        log_debug($log_title . 'end === msg：' . '文件格式不正确');
        parent::endback(['state' => 0, 'msg' => '上传文件必须为excel表格']);
      }
 
 
      //读取表格
      $filename = $_files['file']['tmp_name'];
      $reader = iofactory::createreader('xlsx'); //xls,xlsx都可读取
      $canread = $reader->canread($filename);
      if (!$canread) {
        log_debug($log_title . 'end，文件格式不正确，sql：' . db::name('')->getlastsql());
        parent::endback(['state' => 0, 'msg' => '文件格式不正确', 're_login' => false]);
      }
 
      $spreadsheet = $reader->load($filename); //载入excel表格
      $worksheet = $spreadsheet->getactivesheet(); //选中sheet表
      $highestrow = $worksheet->gethighestrow(); // 总行数
//      $highestcolumn = $worksheet->gethighestcolumn(); // 总列数
 
      if (!(0 < $highestrow)) {
        log_debug($log_title . 'end，文件内容空，sql：' . db::name('')->getlastsql());
        parent::endback(['state' => 0, 'msg' => '文件没有数据', 're_login' => false]);
      }
 
 
      //循环读取--有效判断
      $sst_word_arr = []; //存放敏感词的数组
      for ($row = 1; $row <= $highestrow; $row++) {
        //取列数a列的数据
        $tmp_word = $spreadsheet->getactivesheet()->getcell('a' . $row)->getvalue();
        if ('' != trim($tmp_word) && null != $tmp_word) {
          $sst_word_arr[] = $tmp_word;
          break; //发现有效数据,直接退出,接下来插入数据
        }
      }
//      $sst_word_arr = array_unique($sst_word_arr);
 
      if (empty($sst_word_arr)) {
        log_debug($log_title . 'end，文件无有效数据，sql：' . db::name('')->getlastsql());
        parent::endback(['state' => 0, 'msg' => '文件无有效数据', 're_login' => false]);
      }
 
      //判断和数据库操作
      for ($row = 2; $row <= $highestrow; $row++) {
        //取列数a列的数据
        $tmp_old_car_num = $spreadsheet->getactivesheet()->getcell('a' . $row)->getvalue();
 
        $car_num = trim($tmp_old_car_num);
        if ('' != $car_num && null != $car_num) {
          //数据库操作
          }
        }
      }
 
      $ret_arr = [
        'state' => 1,
         //返回数据
      ];
 
      log_debug($log_title . 'end，success');
      parent::endback($ret_arr);
  } catch (\exception $e) {
      //
    }
  }

excel文件格式为：
