這裏是我的PHP腳本:PHP未定義抵消:1
<?php
$address = htmlentities(strtolower(Config::get('aac.ip')));
$port = Config::get('aac.port');
@$sock = fsockopen ($address, $port, $errno, $errstr, 1);
if(!$sock) echo '<small class="muted"><strong>Server status:</strong></small> <span class="label label-important">OFFLINE</span><br />'; else {
$info = chr(6).chr(0).chr(255).chr(255).'info';
fwrite($sock, $info);
$data='';
while (!feof($sock))$data .= fgets($sock, 1024);
fclose($sock);
// if needed
// var_dump($data);
preg_match('/players online="(\d+)" max="(\d+)"/', $data, $matches);
$players = ''.$matches[1].'/'.$matches[2];
preg_match('/uptime="(\d+)"/', $data, $matches);
$h = floor($matches[1]/3600);
$m = floor(($matches[1] - $h*3600)/60);
$uptime = ''.$h.'h '.$m.'m';
preg_match('/monsters total="(\d+)"/', $data, $matches);
$monsters = ''.$matches[1];
preg_match('#<motd>(.*?)</motd>#s', $data, $matches);
$motd = ''.$matches[1];
preg_match('/npcs total="(\d+)"/', $data, $matches);
$npcs = ''.$matches[1];
if(empty($players) or $players == "/") $players = "???/???";
if(empty($uptime)) $uptime = "???";
if(empty($monsters)) $monsters = "???";
if(empty($motd)) $motd = "???";
echo "

$npcs
";
}
?>
的$npcs
變量返回一個錯誤Undefined offset: 1
。我試圖用很多方式解決這個問題,但都沒有成功。此外,這裏是var_dump數據:
string '<?xml version="1.0"?>
<tsqp version="1.0"><serverinfo uptime="33360" ip="127.0.0.1" servername="Forgotten" port="7171" location="Europe" url="http://otland.net/" server="The Forgotten Server" version="0.2.15" client="9.86"/><owner name="" email="@otland.net"/><players online="2" max="1000" peak="2"/><monsters total="636"/><map name="forgotten" author="Komic" width="1000" height="1000"/><motd>Welcome to the Forgotten Server!</motd></tsqp>
' (length=442)
我試圖檢索信息。另外,我能檢索服務器名稱,位置和類似的東西嗎?我沒有經歷過很多。 :P當您嘗試使用例如不存在的索引來訪問數組項PHP
'$ npcs =''。$ matches [1];'如果這是返回錯誤的行,意味着上面的'preg_match()'可能找不到任何匹配結果 – JLewkovich
''npcs' $ data'因此'$ matches'與'$ npcs'一致是空的。 –
而不是測試$玩家/ $怪物/等。測試你的preg_match比較好。例如:'if(preg_match(........)){/ *做某事* /} else {/ *做其他事情* /}' –
