记录一次使用thinkphp使用PhpSpreadsheet扩展导出数据，解决身份证号码等信息科学计数法问题处理

PhpSpreadsheet官网

PhpSpreadsheet安装

composer require phpoffice/phpspreadsheet

使用composer安装时一定要下载php对应的版本，下载之前使用php -v检查当前php版本

简单使用

<?php

在thinkphp项目中使用

// 如果将该扩展直接安装到thinkphp6项目中提示找不到Class 'PhpOffice\\PhpSpreadsheet\\Spreadsheet' not found，将该扩展放置项目根目录的extend文件夹中（参考下图）,随后打开下行代码
// require_once app()->getRootPath() . 'extend/PhpSpreadsheet/autoload.php';
