正则表达式结合数组提取文章中的文件名

     今天编ZBlog上传模块的时候，需要用到一个提取文章中文件名的子程，开始我把问题想复杂了，匹配了所有可能的文件名，不仅正则表达式写了一大串，而且下面还Split了半天，后来我突然发现Z-Blog的上传文件都存在upload下，白写了那么多复杂的匹配。。。哎，不能浪费掉啊，还是贴上来万一哪个兄弟以后需要也好拿去用~~
  
  下面这段子程基本上可以算是比较不错的通用匹配了。(PS:我突然发现CODE_LITE把我的UBB转义了！！！晕,我只好自己转义了。。。)

  实际上，Z-Blog的话就匹配Upload就可以了（但是我为了省事，也为了更精确些，就干脆在上面的那个匹配上面加上了upload，所以看上去好像下面这个更复杂些，其实理论上应该下面这个简单些，毕竟有upload管着呢。。），也不用SPLit那个/.这么写就可以了：
