PHP如何使用xlswriter进行大数据的导入导出？

最后更新时间：2025-02-16 08:16:57

php xlswriter 导入导出

# 一、准备xlswriter扩展
## 1、windows系统：

到PECL网站下载符合自己本地PHP环境的ddl文件下载地址：https://pecl.php.net/package/xlswriter，并复制到PHP的扩展目录ext文件夹下，修改php.ini文件，

加上这行

```php
extension=xlswriter
```
## 2、Linux系统：

使用命令安装

```php
pecl install xlswriter
```
php配置文件添加

```php
extension = xlswriter.so
```
重启:php nginx 查看PHP安装xlswriter拓展
# 二、封装导出类文件（重点来了）
```php
