PHP支持多格式的解压缩工具类

智云科技发布于 2022年7月22日评论关闭阅读(351)

一、引语

本人在做一个企业云盘项目当中，遇到一个文件在线解压缩的需求，查了网上很多资料，但都是只支持单一格式或部分格式。因此创建了本工具类，对市面上主流的压缩格式进行集成支持，并且简单易用。

二、功能

​1.支持zip、rar、phar、tar、gz、bz2、7z格式的解压；

2.支持对单文件、多文件、文件夹进行压缩成zip文件格式数据库连接池。​

​​

三、前置条件

​1. 安装php_zip插件：用于解压缩zip格式文件

2. 安装php_rar插件：用于解压缩rar格式文件

3. 安装php_phar插件：用于解压缩phar、tar、gz、bz2格式文件

4. 安装p7zip p7zip-full软件：用于解压缩7z格式文件​

四、实现 

 class ZipUtil

{

    /**

     * 解压

     * @param string $zipFilePath 压缩文件路径

     * @param string $toDirPath 解压目录路径

     * @return string

     * @throws \Exception

     */

下期会分享应用配置管理演变及apollo概念拆解哦，敬请期待~
