Using PHPExcel in thinkphp5.0+

1. Install PHPExcel

1. The TP5 version can be installed directly using composer (composer will not find the tutorial by yourself):
composer require phpoffice/phpexcel

Very convenient.

2. Download PHPExcel from the official website, and then put it in the vendor directory or in the extend directory (the following is to put it in the extend directory)

2. Introduce the PHPExcel class into the control page

EXTEND_PATH. The path to PHPExcel.php in your PHPExcel

1. Generate an excel instance

2. Export an excel sheet and save it to the local

3. Download data from database to generate excel

1. Encapsulate database data

2. Encapsulate the excel download function

3. Test

Enter your test address in the browser and it will pop up

download successful

Fourth, the overall code

<?php
namespace app\home\controller;
require_once EXTEND_PATH.'PHPExcel/Classes/PHPExcel.php';
