使用PHP查询Shoutcast服务器是脱机还是联机

Question

I'm trying to use a script to query if a Shoutcast Server is online or offline. The code below is what I'm using at the moment.

$vt_ip = "ip";
$vt_port = "port";

$output = @fsockopen($vt_ip, $vt_port, $errno, $errstr, 2);

if (!$output) {
echo "<FONT CLASS=f1 COLOR=#DD0000><B>OFFLINE</B></FONT>";
} else {
echo "<FONT CLASS=f1 COLOR=#00DD00><B>ONLINE</B></FONT>";
}

@fclose($output);

But it doesn't update, it is stuck on Offline status.

Any help would be greatly appreciated.

Answer 1

$vt_ip = "ip";
$vt_port = "port";

$conn = fsockopen($vt_ip, $vt_port, $errno, $errstr, 2);

if(!$conn){
    echo $errno;
}else{

fwrite($conn, "\n");
$output = fread($conn, 1024);
fclose($conn);

if ($output == "") {
    echo "<FONT CLASS=f1 COLOR=#DD0000><B>OFFLINE</B></FONT>";
} else {
        echo "<FONT CLASS=f1 COLOR=#00DD00><B>ONLINE</B></FONT>";
    }
}

Answer 2

It isn't enough to simply make a TCP connection to a SHOUTcast server to determine if the stream is working. In fact, a SHOUTcast server that is running will always accept yourTCP connection, even if there is no stream for playback.

You must connect, request the stream, and then check the return status code. Once connected, send this data:

GET /; HTTP/1.0

Follow that by a \\r\\n\\r\\n . Now, read data back from the stream until you get the \\r\\n\\r\\n . Then, you can disconnect. Check the status code from the first response line and see if it's 200 . If it is, you've got an active stream.
