我正在尝试将我的 PHP 脚本连接到 IRC，但它一直超时。我在服务器上，所以我知道它已经启动并正在运行，我不知道问题是什么。
这可能是我的代码中的错误吗？
<?php
/**
* Configuration.
* Pretty self-explanatory
*/
$ircServer = "hub.malvager.com";
$ircPort = "6667";
$ircChannel = "#hackforums";
set_time_limit(0);
$ircSocket = fsockopen($ircServer, $ircPort, $eN, $eS);
if ($ircSocket)
{
fwrite($ircSocket, "USER Orgy orgy.test hfcoder :twBooter\n");
fwrite($ircSocket, "NICK OrgyBot|" . rand() . "\n");
fwrite($ircSocket, "JOIN " . $ircChannel . "\n");
while(1)
{
while($data = fgets($ircSocket, 128))
{
echo nl2br($data);
flush();
// Separate all data
$exData = explode(' ', $data);
// Send PONG back to the server
if($exData[0] == "PING")
{
fwrite($ircSocket, "PONG ".$exData[1]."\n");
}
}
}
}
else
{
echo $eS . ": " . $eN;
}
?>
更新：显然，它在某些服务器上成功运行，但在其他服务器上却没有。fsockopen 是允许的，set_time_limit 也是如此。我无法弄清楚问题是什么。
更新：这是一个跟踪路线：
