一、引语
本人在做一个企业云盘项目当中，碰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举行集成支持，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、文件夹举行压缩成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

调用：
//示例1：解压zip文件到/test/test1/目次下ZipUtil::extract('/test/test1.zip', '/test/test1/');//示例2：解压rar文件到/test/test2/目次下ZipUtil::extract('/test/test2.rar', '/test/test2/');//示例3：解压phar文件到/test/test3/目次下ZipUtil::extract('/test/test3.phar', '/test/test3/');//示例4：解压tar文件到/test/test4/目次下ZipUtil::extract('/test/test4.tar', '/test/test4/');//示例5：解压gz文件到/test/test5/目次下ZipUtil::extract('/test/test5.tar.gz', '/test/test5/');//示例6：解压bz2文件到/test/test6/目次下ZipUtil::extract('/test/test6.tar.bz2', '/test/test6/');//示例7：解压7z文件到/test/test7/目次下ZipUtil::extract('/test/test7.7z', '/test/test7/');//示例8：压缩单个文件ZipUtil::packageFile('/test/test8/1.txt', '/test/test8.zip');//示例9：压缩多个文件ZipUtil::package([ ['file_type'=>'file', 'file_path'=>'/test/test9/1.txt', 'local_name'=>'1.txt'], ['file_type'=>'file', 'file_path'=>'/test/test9/2.txt', 'local_name'=>'2.txt'], ['file_type'=>'folder', 'local_name'=>'1/'], ['file_type'=>'folder', 'local_name'=>'2/'],], '/test/test9.zip');//示例10：压缩文件夹ZipUtil::packageDir('/test/test10/', '/test/test10.zip');1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.22.23.24.25.26.27.28.29.30.31.32.33.34.35.36.37.38.39.40.41.42.43.44.45.46.47.48.49.50.51.52.53.54.55.56.57.58.59.60.61.62.63.64.65.66.67.68.69.70.71.72.73.74.75.76.
五、结语
在刚开始使用这个工具类的过程中，发现在了个坑，就是在window压缩的zip文件放到linux举行解压会发生文件名乱码的情况，所以不能直接使用extractTo方法举行解压，需要对zip解压出来的文件名举行转码。
以上是本期分享的全部内容，主要讲解通过PHP对主流的压缩格式举行集成支持，简单易用。
下期会分享应用配置管理演变及apollo概念拆解哦，敬请等待~
