版本发布 - 上次看到`sf`使用php的phar来更新版本，弱弱的问几个问题！
提问之前粗略的看了下网上教程，云里雾里的。
Q1：使用phar打包需要对现在的代码做特殊处理吗？比如我现在的项目，如果用这种方式往正式服务器更新版本，需要修改以前的代码否？
Q2：比如我打包成了project.phar，之前的项目入口是Index.php，那么打包之后直接改apache的索引文件增加一个project.phar就行了？
Q3:怎样才能无缝更新版本？我之前都是先把新版本文件上传完，然后修改以前网站文件夹名字（比如加一个_20141030），然后把刚上传的文件夹名字改为以前网站文件夹的名字！但是这样也会有大概3s~5s左右的中断。
Q2我等下下班之后自己试一下！可无视！
