[转] flash socket与php socket通信的例子
http://bbs.9ria.com/viewthread.php?tid=76152&extra=page%3D1%26amp%3Borderby%3Ddateline%26amp%3Bfilter%3D2592000
使用说明:
1:把socket这个文件夹复制到硬盘，比如盘符是d:\
2:找到socket\php下面的start.bat,右键--编辑---修改盘符（这里默认地址是d:\）
3:把socket文件夹下的xx.cfg复制到C:\Documents and Settings\hui.wang\Application Data\Macromedia\Flash Player\#Security\FlashPlayerTrust下。
4:双击php\socket下的start.bat,运行服务端。可以查看服务端运行状况。
5:双击flash\load.swf运行，点击舞台，可以收到服务端数据。
6:Server.php里已经默认发送crossdomain.xml字符,防止安全沙箱冲突。
