PHP前端

Question

我又遇到了一个问题，我想在ShoutCast2中使用这个API，并且有一个数组问题。

$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);

数组输出：

Array (
    [@attributes] => Array (
        [seq] => 128
    )
    [data] => Array (
        [eventlist] => Array (
            [event] => Array (
                [@attributes] => Array (
                    [type] => relay
                )
                [relay] => Array (
                    [@attributes] => Array (
                        [priority] => 1
                        [url] => IP:PORT
                    )
                )
                [active] => 1
                [id] => 1
                [calendar] => Array (
                    [@attributes] => Array (
                        [starttime] => 00:00:00
                    )
                )
            )
        )
    )
)

现在，我想通过数组读取输出：

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

        echo $event ->type;


    }

为什么没有问题？错误在哪里？

谢谢

编辑原始XML

<eventlist>
 <event type="playlist|dj|relay">
   <active/>
   <id/>
   <dj/>
   <playlist loopatend="1|0" shuffle="1|0" priority="#">
     nameofplaylist
   </playlist>
   <relay url=""/>
   <calendar/>
 </event>
 <event ... />

打印SimpleXML元素无助于您。其中的数据是类的内部数据。

你只想简单地这样做：

foreach($xml->event as $event){
    echo (string)$event['type'];
}
