解析PHP socket_listener上的套接字数据

Question

I was able to open a PHP TCP listener socket, but I don't know how to parse the buffer. The client that connects to my socket send a text/html with an additional boundary data with a xml file and an image file.

How can I parse the response to get the XML file on one side and the Image on the other side?

server = socket_create_listen(8086);
socket_getsockname($server, $addr, $port);
if (!$server) {
    $message = 'Start TCP socket: Ko. Could not create socket.';
    $this->logger->info($message);
    die($message);
} else {
    $message = 'Start TCP socket: Ok. TCP socket opened on: ' . $addr . ':' . $port . '.';
    $this->logger->info($message);

    while ($c = socket_accept($server)) {
        socket_getpeername($c, $raddr, $rport);
        $this->logger->info("Received Connection from $raddr:$rport
");

        $data = '';
        while ($bytes = socket_recv($c, $r_data, 1024, MSG_WAITALL)) {
            $data .= $r_data;
        }

        //Edited: Explode with double line and got data
        $parsedData = explode("

", $data);
        $xml = new \SimpleXMLElement($parsedData[2]);

        print_r($xml);

        else {
            echo "socket_recv() failed; reason: " . socket_strerror(socket_last_error($c)) . "
";
        }

        socket_close($c);
    }
}
fclose($server);

This is the output I received:

EDITED: I was able to got the XML data by using "explode" function, but I don't know how to get the 2 images as image files. Any suggestion?

Any help would be really appreciated!

Thank you!
