前段时间我使用 query 来检查 minecraft 服务器的状态.php，但我对结果不太满意。有时它只需要 10 多秒，或者甚至没有获得状态，尽管 mc 服务器已启动并且 Web 服务器位于同一数据中心内。
您认为哪种方法最稳定且性能最好：查询、stream_stocket或其他方法？
我应该每 30 秒通过 cronjob 运行一次测试，还是只将结果缓存 30 秒？
您可以使用此代码创建一个 PHP 文件，并定期运行以存储状态。

function mc_status($host,$port='25565') {
$timeInit = microtime();
// TODO: implement a way to store data (memcached or MySQL?) - please don't overload target server
$fp = fsockopen($host,$port,$errno,$errstr,$timeout=10);
if(!$fp) die($errstr.$errno);
else {
fputs($fp, "'xFE"); // xFE - get information about server
$response = '';
while(!feof($fp)) $response .= fgets($fp);
fclose($fp);
$timeEnd = microtime();
$response = str_replace("'x00", "", $response); // remove NULL
//$response = explode("'xFF", $response); // xFF - data start (old version, prior to 1.0?)
$response = explode("'xFF'x16", $response); // data start
$response = $response[1]; // chop off all before xFF (could be done with regex actually)
//echo(dechex(ord($response[0])));
$response = explode("'xA7", $response); // xA7 - delimiter
$timeDiff = $timeEnd-$timeInit;
$response[] = $timeDiff < 0 ? 0 : $timeDiff;
}
return $response;
}
$data = mc_status('mc.exs.lv','25592'); // even better - don't use hostname but provide IP instead (DNS lookup is a waste)
print_r($data); // [0] - motd, [1] - online, [2] - slots, [3] - time of request (in microseconds - use this to present latency information)
