如何不显示shell的返回信息
用PHP写的脚本:
shell_exec('/usr/local/memcached/bin/memcached -u root'); // 启动memcached 
搁在终端下直接执行该命令或者解析执行这个PHP文件,进程就都一直挂着,如果关闭终端就会杀死这个memcached进程(它不像Apache那样启动后也就完事了)。
有什么办法,PHP脚本发出命令后再不去管,或者是让memcached进程不要挂在终端上,这让强迫症患者很难受

------解决方案--------------------
@shell_exec('/usr/local/memcached/bin/memcached -u root');
@:屏蔽错误或警告的显示!
