In many cases we will need to upload tables to the database in batches, so today I will teach you how to use PHP to upload tables in batches.

First of all, you need to download PHPExcel and put it in the vendor folder. My path is: project/vendor/PHPExcel/, put the downloaded PHPExcel file here

Front-end code

<!DOCTYPE html>
<html>
<head>
  <title>批量导入数据</title>
</head>
<body>
<form action="{:url(&#39;/index/index/importExcel&#39;)}" method="post" enctype="multipart/form-data">
  <input type="file" name="myfile"><br/>
  <input type="submit" value="批量的导入">
</form>
</body>
</html>

Backend code

/**
  * 导入表格数据
  * 先把文件上传到服务器，然后再读取数据存到数据库
  */
  public function importExcel(){
    header("content-type:text/html;charset=utf-8");
    //上传excel文件
    $file = request()->file(&#39;myfile&#39;);
    //移到/public/uploads/excel/下
    $info = $file->move(ROOT_PATH.&#39;public&#39;.DS.&#39;uploads&#39;.DS.&#39;excel&#39;);
    //上传文件成功
    if ($info) {
      //引入PHPExcel类
      vendor(&#39;PHPExcel.PHPExcel.Reader.Excel5&#39;);
      //获取上传后的文件名
      $fileName = $info->getSaveName();
      //文件路径
      $filePath = &#39;public/uploads/excel/&#39;.$fileName;
      //实例化PHPExcel类
      $PHPReader = new \PHPExcel_Reader_Excel5();
      //读取excel文件
      $objPHPExcel = $PHPReader->load($filePath);
      //读取excel文件中的第一个工作表
      $sheet = $objPHPExcel->getSheet(0);
      $allRow = $sheet->getHighestRow();  //取得总行数
      //$allColumn = $sheet->getHighestColumn();  //取得总列数
      //从第二行开始插入，第一行是列名
      for ($j=2; $j <= $allRow; $j++) {
        $data[&#39;name&#39;] = $objPHPExcel->getActiveSheet()->getCell("A".$j)->getValue();
        $data[&#39;tel&#39;] = $objPHPExcel->getActiveSheet()->getCell("B".$j)->getValue();
        $data[&#39;addr&#39;] = $objPHPExcel->getActiveSheet()->getCell("C".$j)->getValue();
        $last_id = Db::table(&#39;users&#39;)->insertGetId($data);//保存数据，并返回主键id
        if ($last_id) {
          echo "第".$j."行导入成功，users表第:".$last_id."条！<br/>";
        }else{
          echo "第".$j."行导入失败！<br/>";
        }
      }
    }else{
      echo "上传文件失败！";
    }
  }

Note:

Introduce third party Class libraryUse vendor( ); is in the form of namespace. The underlying code will automatically replace "." with "/", so when using "/", use "." instead;

The above code can be copied and used directly, but the database related information must be changed to your own !

# I believe you have mastered the methods after reading these cases. For more exciting information, please pay attention to other related articles on the php Chinese website!
