Thinkphp6实现Excel导入功能

tp6实现Excel导入很简单，实现步骤如下：

1、使用composer安装PHPExcel

composer require phpoffice/phpexcel

2、执行composer更新

composer update

3、代码实现

<?php
declare (strict_types = 1);

namespace app\union\controller;

use app\Request;
use app\union\model\Groups;
use think\facade\Cookie;
use think\facade\Db;
use think\facade\View;
use PHPExcel_IOFactory;	//通过composer加载的第三方类，直接在头部引入一下就可以

class Group extends Base
{
	    public function import_save(Request $request){
        if(!$request->param('excel')){
            return returnJson('500','请上传excel文件');
        }
        $path = public_path().$request->param('excel');

        //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($path)) {
            $PHPReader = new \PHPExcel_Reader_Excel5();
            if (!$PHPReader->canRead($path)) {
                return returnJson('500','请上传excel文件');
            }
        }
        //读取Excel文件
        $PHPExcel = $PHPReader->load($path);
        //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
            $data = [
                'number'=>$PHPExcel->getActiveSheet()->getCell("A" . $currentRow)->getValue(),
                'nickName'=>$PHPExcel->getActiveSheet()->getCell("B" . $currentRow)->getValue(),

                'shop_name'=>$PHPExcel->getActiveSheet()->getCell("H" . $currentRow)->getValue(),
                'remarks'=>$PHPExcel->getActiveSheet()->getCell("I" . $currentRow)->getValue(),
                'status'=>0,
                'created_at'=>date('Y-m-d')
            ];
            if($data['number'] == ''){
                $result = 1;
                continue;
            }else{
                $find = Groups::where(array('number'=>$data['number']))->find();
                if($find){
                    $result = 1;
                    continue;

                }else{
                    $result=Db::name('group')->insert($data);
                }
            }

        }
        if($result){
            return returnJson('200','导入成功');
        }else{
            return returnJson('500','导入失败');
        }
    }
    public static function get_date_by_excel($date){
        if (!$date || $date == '0000-00-00') return null;

        $unix_time = \PHPExcel_Shared_Date::ExcelToPHP($date);

        return gmdate('Y-m-d H:i',$unix_time);
