Example of how to import data from Excel files to MySQL database

Recently I am importing data from Excel files into the database. If the website wants to support batch insertion of data, it can create a small program that uploads Excel files and imports the data content into the MySQL database. This article mainly shares with you examples of how to import data from Excel files to MySQL database. I hope it can help you.

Tools to be used:

ThinkPHP: lightweight domestic PHP development framework. It can be downloaded from ThinkPHP official website.

PHPExcel: A PHP class library for Office Excel documents, which is based on Microsoft's OpenXML standard and PHP language. It can be downloaded from the CodePlex official website. ,

1. Design MySQL database product

Create product database

CREATE DATABASE product DEFAULTCHARACTER SET utf8 COLLATE utf8_general_ci;

Create pro_info table, table structure

CREATE TABLE pro_info(
pId int(4)NOT NULL PRIMARY KEY AUTO_INCREMENT,
pName varchar(20)NOT NULL,
pPrice floatNOT NULL,
pCount floatNOT NULL
);

2. Generate the project

First create a new index.php file in the same directory as ThinkPHP and generate the project Home.

3. Upload file form

<?php
  
define(&#39;APP_NAME&#39;,&#39;Home&#39;);  //项目名称
define(&#39;APP_PATH&#39;,&#39;./Home/&#39;); //项目路径
define(&#39;APP_DEBUG&#39;, true);  //开启DEBUG
require &#39;./ThinkPHP/ThinkPHP.php&#39;;  //引入ThinkPHP核心运行文件
?>

Create a new Index folder under the Home/Tpl folder, and create a new index.html file inside it

<!DOCTYPE html>
  
<html>
  <head>
    <title>上传文件</title>
    <metacharset="UTF-8">
  </head>
  <body>
    <formid="upload"action="__URL__/upload/"method="post"enctype="multipart/form-data">
      <labelfor="file">上传文件:</label>
      <inputtype="file"name="file"id="file"><br/>
      <inputtype="submit"name="submit"value="上传"/>
    </form>
  </body>
</html>

4. Write methods to display the upload form page, upload Excel files, and import Excel files in /Home/Lib/Action/IndexAction.class.php (if there is no expansion package under ThinkPHP/Extend, you need Download it from the ThinkPHP official website, and then unzip the extension package and put it in)

<?php
  
/**
*
* 导入Excel文件数据到MySQL数据库
*/
class IndexAction extends Action {
  
  /**
   * 显示上传表单html页面
   */
  publicfunction index() {
    $this->display();
  }
  
  /**
   * 上传Excel文件
   */
  publicfunction upload() {
    //引入ThinkPHP上传文件类
    import(&#39;ORG.Net.UploadFile&#39;);
    //实例化上传类
    $upload= new UploadFile();
    //设置附件上传文件大小200Kib
    $upload->mixSize = 2000000;
    //设置附件上传类型
    $upload->allowExts =array(&#39;xls&#39;,&#39;xlsx&#39;, &#39;csv&#39;);
    //设置附件上传目录在/Home/temp下
    $upload->savePath =&#39;./Home/temp/&#39;;
    //保持上传文件名不变
    $upload->saveRule =&#39;&#39;;
    //存在同名文件是否是覆盖
    $upload->uploadReplace = true;
    if(!$upload->upload()) { //如果上传失败,提示错误信息
      $this->error($upload->getErrorMsg());
    }else {  //上传成功
      //获取上传文件信息
      $info= $upload->getUploadFileInfo();
      //获取上传保存文件名
      $fileName= $info[0][&#39;savename&#39;];
      //重定向,把$fileName文件名传给importExcel()方法
      $this->redirect(&#39;Index/importExcel&#39;,array(&#39;fileName&#39;=> $fileName), 1,&#39;上传成功！&#39;);
    }
  }
  
  /**
   *
   * 导入Excel文件
   */
  publicfunction importExcel() {
    header("content-type:text/html;charset=utf-8");
    //引入PHPExcel类
    vendor(&#39;PHPExcel&#39;);
    vendor(&#39;PHPExcel.IOFactory&#39;);
    vendor(&#39;PHPExcel.Reader.Excel5&#39;);
  
    //redirect传来的文件名
    $fileName= $_GET[&#39;fileName&#39;];
  
    //文件路径
    $filePath= &#39;./Home/temp/&#39; . $fileName . &#39;.xlsx&#39;;
    //实例化PHPExcel类
    $PHPExcel= new PHPExcel();
    //默认用excel2007读取excel，若格式不对，则用之前的版本进行读取
    $PHPReader= new PHPExcel_Reader_Excel2007();
    if(!$PHPReader->canRead($filePath)) {
      $PHPReader= new PHPExcel_Reader_Excel5();
      if(!$PHPReader->canRead($filePath)) {
        echo&#39;no Excel&#39;;
        return;
      }
    }
  
    //读取Excel文件
    $PHPExcel= $PHPReader->load($filePath);
    //读取excel文件中的第一个工作表
    $sheet= $PHPExcel->getSheet(0);
    //取得最大的列号
    $allColumn= $sheet->getHighestColumn();
    //取得最大的行号
    $allRow= $sheet->getHighestRow();
    //从第二行开始插入,第一行是列名
    for($currentRow = 2; $currentRow <= $allRow; $currentRow++) {
      //获取B列的值
      $name= $PHPExcel->getActiveSheet()->getCell("B". $currentRow)->getValue();
      //获取C列的值
      $price= $PHPExcel->getActiveSheet()->getCell("C". $currentRow)->getValue();
      //获取D列的值
      $count= $PHPExcel->getActiveSheet()->getCell("D". $currentRow)->getValue();
  
      $m= M(&#39;Info&#39;);
      $num= $m->add(array(&#39;pName&#39;=> $name,&#39;pPrice&#39; => $price, &#39;pCount&#39;=> $count));
    }
    if($num > 0) {
      echo"添加成功！";
    }else {
      echo"添加失败！";
    }
  }
  
}
?>
