php6环境下运行thinlphp 3.2最新版出现错误：Warning: Unexpected character in input: '\' (ASCII=92) state=0 in E:\AppServ\www\ThinkPHP\ThinkPHP\ThinkPHP.php on line 96

Parse error: syntax error, unexpected T_STRING in E:\AppServ\www\ThinkPHP\ThinkPHP\ThinkPHP.php on line 96

我是appserv 2.6环境，才接触thinkphp，麻烦大家帮帮忙，查看是这行代码出的错 Think\Think::start();
