curl post array Shoutcast2

[m-eye]

I have again a problem, I want to use in ShoutCast2 the API and have an array a problem.

$sc_host = 'IP';
$sc_port = 'PORT';
$sc_user = 'USER';
$sc_pass = 'PASSWORD';
mt_srand((double) microtime() * 1000000);
$seq  = mt_rand(1, 100);
$post = 'op=listevents&seq=' . $seq;
$ch   = curl_init($sc_host . '/api');
curl_setopt($ch, CURLOPT_PORT, $sc_port);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, $sc_user . ':' . $sc_pass);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$curl = curl_exec($ch);
$xml  = new SimpleXMLElement(utf8_encode($curl));
curl_close($ch);

Array var_dump Output:

object(SimpleXMLElement)#2 (2) {
  ["@attributes"]=>
  array(1) {
    ["seq"]=>
    string(2) "44"
  }
  ["data"]=>
  object(SimpleXMLElement)#3 (1) {
    ["eventlist"]=>
    object(SimpleXMLElement)#4 (1) {
      ["event"]=>
      object(SimpleXMLElement)#5 (5) {
        ["@attributes"]=>
        array(1) {
          ["type"]=>
          string(5) "relay"
        }
        ["relay"]=>
        object(SimpleXMLElement)#6 (1) {
          ["@attributes"]=>
          array(2) {
            ["priority"]=>
            string(1) "1"
            ["url"]=>
            string(18) "127.0.0.1:8000"
          }
        }
        ["active"]=>
        string(1) "1"
        ["id"]=>
        string(1) "1"
        ["calendar"]=>
        object(SimpleXMLElement)#7 (1) {
          ["@attributes"]=>
          array(1) {
            ["starttime"]=>
            string( "00:00:00"
          }
        }
      }
    }
  }
} 

Now I want to read the output via array

foreach ($xml->data->eventlist->event as $event ) {

        echo $event ->type;


    }

no issue is why? where is the error?

Thank you
