不显示前面的记录号。你可以加上off和不加off都执行一下，就可以看到区别了

计算机中displayoff是什么意思
意思是显示器关闭。 一、显示器关闭原因：1、电脑主机问题 因为黑屏的时候都是发生在待机状态 电脑在待机一定时间以后会将显示器关闭以进入节能状态 但是有的主机能正常待机 等你想用机器的时候退出待机状态就出问题 电脑无响应了 也就是说他不能转变回正常工作状态了 当然显示器没有收到主机开启的信号也不会亮起来 如果待机的时候黑屏你按一下键盘任意键 如果硬盘等闪烁 说明主机能在正常和待机状态中切换 那就往下看。 2、显卡问题 有的显卡问题就是频繁黑屏 无明显规则 属于硬件问题 如果显卡不正常输出显示器所需的正常行场信号，显示器就会由绿灯变为红灯的待机状态，如果你确定电脑系统没问题 显卡驱动没问题 那就是显卡本身有问题了 建议如果是新买的电脑尽快去经销商那里检测更换。

Announcing Stack Overflow Documentation
We started with Q&A. Technical documentation is next, and we need your help.
Whether you're a beginner or an experienced developer, you can contribute.
Curious. I'm starting to broadcast high school football games online, and it uses a program to broadcast the feeds off my computer. However, when I shut the program down or the computer down, the server goes offline and guests won't be able to access the feeds.
Is there any kind of code out there that I can post onto my website that will indicate to my guests whether the server is on or off? I would figure it would be a simple code, a php script or something that periodically checks to see if a site is on line and then displays ON or OFF.
EDIT: use @fsockopen or you'll get a Cannot connect to the server warning which you can ignore since that is what you're actually trying to check.
$ping = @fsockopen('myURL or IP', 80, $errno, $errstr, 10);
if (!$ping) // site is down
$URL = '';
$ping = @fsockopen ($URL, 80, $errno, $errstr, 10);
(!$ping) ? $status = $URL.' is down' : $status = $URL.' is up';
echo $status.'&br&';
$URL = '';
$ping = @fsockopen ($URL, 80, $errno, $errstr, 10);
(!$ping) ? $status = $URL.' is down' : $status = $URL.' is up';

Two options here, the first is you can request a response from the remote server and if it doesn't exist (after some timeout) claim that it's offline. You can cache this if response times can be slower then the time users will want to wait, or shove this into an AJAX request that can then remove the video player, display the notice, etc. on failure.
The other alternative is to check for feed failure and display a server offline message.
You can use the PEAR-Package "" to ping your server.
