laravel maatwebsite/excel 导出Excel

1、首先查看vendor 文件夹中有没有 maatwebsite/excel 依赖，若没有在项目根目录下使用Composer安装依赖

composer require "maatwebsite/excel:~2.1.0"

2、在config/app.php中注册服务提供者到providers数组

Maatwebsite\Excel\ExcelServiceProvider::class,

　在config/app.php中注册门面到aliases数组

'Excel' => Maatwebsite\Excel\Facades\Excel::class,

　如果想要对Laravel Excel进行更多的自定义配置，执行如下Artisan命令

php artisan vendor:publish

　执行成功后会在config目录下生成一个配置文件excel.php

3、导出 Excel 文件

创建ExcelController.php

<?php

namespace App\Http\Controllers\Admin;

use Illuminate\Foundation\Application;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Artisan;
use App\Models\Member;
use App\Models\SpecialSubject;
use Excel;
use PHPExcel_Worksheet_Drawing;

class ExcelController extends Controller
{
    public function export(Request $request){
        ini_set('memory_limit','500M');
        set_time_limit(0);//设置超时限制为0分钟
        
        $info = Member::select('avatar','nickname','gender','wx_country','wx_province','wx_city','realname','mobile','company_name','email','is_news','industry','position','province','city','region','is_access','interest','is_enroll','prev_path')->get()->toArray();
               
        foreach($info as $k=>$v){
            $kk = $k + 1;
            // $cellData[$kk]['avatar'] = $v['avatar'];
            $cellData[$kk]['nickname'] = $v['nickname'];
            if($v['gender'] == 2){
                $cellData[$kk]['gender'] = '女';
            }else{
                $cellData[$kk]['gender'] = '男';

            if($v['is_news'] == 1){
                $cellData[$kk]['is_news'] = '是';

            $cellData[$kk]['position'] = $v['position'];
            $cellData[$kk]['company_address'] = $v['province'].$v['city'].$v['region'];
            if($v['is_access'] == 1){
                $cellData[$kk]['is_access'] = '是';
            }else{
                $cellData[$kk]['is_access'] = '否';
            }
            
            $ids = explode(',',$v['interest']);
            $list = SpecialSubject::whereIn('id',$ids)->get(['id','title','short'])->toArray();
            
            $name = [];
            foreach($list as $vv){
                $name[] = $vv['title'].$vv['short'];
            }
            $cellData[$kk]['interest'] = implode(',',$name);
            if($v['is_enroll'] == 1){
                $cellData[$kk]['is_enroll'] = '是';
            }else{
                $cellData[$kk]['is_enroll'] = '否';
            }
            $cellData[$kk]['prev_path'] = $v['prev_path'];
        }
        // 设置表头
        $cellData[0] = array('用户名','性别','地区','姓名','手机号','公司名称','公司邮箱','是否接收资讯更新','所属行业','职位','公司所在地','是否已接入穿山甲','感兴趣的话题','是否报名','补全资料的前一个路径');
        // 把需要导出的数据遍历成一个数组
        for($i=0;$i<count($cellData);$i++){

    }

定义相关路由，在浏览器访问即可；
