【PHP】SVN版本差异导出

<?php
/**
 * 导出指定版本之间的差异文件,如 100 和 200 之间的差异则导出 100(不包括) - 200(包括) 的所有修改
 * 【SVN命令行】
 * 1、查看版本间差异
 * svn diff -r 2359:2360 --summarize --username heyw --password 123123 svn://192.168.0.10/rrc_cli
 * 2、导出某个版本文件到本地
 * svn export -r 2360 svn://192.168.0.10/rrc_cli/common/controller/WechatBaseController.class.php /tmp/rrc_cli/common/controller/WechatBaseController.class.php --username heyw --password 123123
 *
 * @example svn.php 60 62:63 70
 * @author heyw
