php生成curl命令行

e.g.

curl “http://localhost/other/serverInfo.php?dd=ddd” -H “Host:localhost” -H “Connection:keep-alive” -H “Cache-Control:max-age=0” -H “Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8” -H “User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.132 Safari/537.36” -H “DNT:1” -H “Accept-Encoding:deflate, sdch” -H “Accept-Language:zh-CN,zh;q=0.8,en;q=0.6” -H “Cookie:name=richie; email=[e-mail]”

            throw new Exception("cli");
