ThinkPHP6 excel 导入功能完整实现

在 ThinkPHP 6.0 中实现 excel 导入导出功能，需要使用第三方库或扩展，例如 phpspreadsheet。

安装
项目目录下打开命令行，执行命令：

composer require phpoffice/phpspreadsheet

use PhpOffice\PhpSpreadsheet\IOFactory;


添加路由
上传文件改用post提交

Route::post('productImport', 'ProductOrder/importExcel');
实战代码
/**
 * excel 导入
 * @return false|string
 */
public function importExcel()
{
    $file = request()->file('file');
    if (!$file) {
        print_r('请选择需要导入的文件');die;
    }
 
    // 加载文件
    $spreadsheet = IOFactory::load($file->getRealPath());
    $sheet = $spreadsheet->getActiveSheet();
 
    // 处理文件数据
    $data = [];
    foreach ($sheet->getRowIterator() as $row) {
        $rowIndex = $row->getRowIndex();
        // 不读取第一行 标题
        if ($rowIndex == 1) {
            continue;
        }
        $cellIterator = $row->getCellIterator();
        $row = [];
        foreach ($cellIterator as $cell) {
            $row[] = $cell->getValue();
        }
        $data[] = $row;
    }
 
    // 数据入库处理
 
 
    print_r($data);die;
}

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(),

                '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;
