Question

我试图集成一个php脚本，如果特定服务器处于脱机状态或在线状态，每30秒检查一次，然后appropriatley打印我的Drupal 7.23网站上的状态。

我想出了下面的代码，但php脚本报告服务器一直处于脱机状态，即使它处于联机状态。我不知道是什么问题。

<div class="serverstatus">  
<?php
ini_set( "display_errors", 0);  //hide fsockopen/fopen warnings if file doesn't exist or couldn't connect
$g_Status = 0;

$g_Ip = "0.0.0.0";  //Server ip
$g_Port = "0000";   //Server Port

function IsOnline($ip, $port)
{
    $sock=@fsockopen($ip, $port, $errNo, $errStr, 3);//timeout set to 3 seconds
    if($sock)
    {
        fclose($sock);
        return 1;
    }
    return 0;
}

function RefreshStatus()
{
    global $g_Ip, $g_Port;
    $status = IsOnline($g_Ip, $g_Port);
    //storing info about timestamp and server status
    $file = fopen("status.txt", "wb");
    $timestamp = time() + 30;   //it will refresh every 30 seconds - won't flood the server
    $cont = $timestamp .' '. $status;
    fwrite($file, $cont);
    fclose($file);
    return $status;
}

$file = fopen("status.txt", "r");
if(!$file)
{
    //file doesn't exist
    $g_Status = RefreshStatus();
}else
{
    $cont = fread($file, filesize("status.txt"));
    $data = explode(" ", $cont);    //$data[0] is our timestamp and $data[1] is our server status
    if($data[0] < time())
    {
        //refresh status
        $g_Status = RefreshStatus();
    }else
    {
        $g_Status = $data[1];
    }
}

//Display server status
if($g_Status)
{
    echo "Online";
}else
{
    echo "Offline";
}

?>
</div>

我非常感谢所有答案！谢谢你，并致以最诚挚的问候。

好吧，我让它工作，以便准确报告服务器。我还是不确定出了什么问题但很好，它的方式更简单，如果有人想知道如何连接drupal 7与Lineage 2专用服务器来检查状态，这里是代码：

<div class="serverstatus">  
<?php
$server = "server ip";
$portg = "game server port";
$portl = "login server port";
$timeout = "1";

$game = @fsockopen("$server", $portg, $errno, $errstr, $timeout);
$login = @fsockopen("$server", $portl, $errno, $errstr, $timeout);

    echo "Login Server: ";
    echo $login ? "<font color=\"green\">OnLine</font>" : "<font color=\"red\">Off line</font>";
    echo "<br>Game Server: ";
    echo $game ? "<font color=\"green\">OnLine</font>" : "<font color=\"red\">Off line</font>";
?>
</div>

感谢所有的答案，问候。
