shoutcasts脚本还有其他内容可以读取它的XML文件吗？
我目前有：
<?php
$open = fsockopen("62.75.171.171","9992");
if ($open) {
fputs($open,"GET /7.html HTTP/1.1\nUser-Agent:Mozilla\n\n");
$read = fread($open,1000);
$text = explode("content-type:text/html",$read);
$text = explode(",",$text[1]);
} else { $er="Connection Refused!"; }
?>
</div>
<?php
if ($text[1]==1) { $state = "Up"; } else { $state = "Down"; }
if ($er) { echo $er; exit; }
echo "<font face=verdana size=1>
Listeners: $text[0] of $text[3] ($text[4] Unique)<br>
Listener Peak: $text[2]<br>
Server State: <b>$state</b><br>
Bitrate: $text[5] Kbps<br>
Current Song: $text[6]
Current DJ: $text[13]
</font>";?>
<?php
echo "<IMG src='http://thepilotslife.com/images/shows/{$text[13]}.png'></img>";
?>
但是给了我这些错误：
Notice: Undefined variable: er in C:\xampp\htdocs\stats.php on line 13
Notice: Undefined offset: 13 in C:\xampp\htdocs\stats.php on line 20
Listeners: 0 of 150 (0 Unique)
Listener Peak: 1
Server State: Up
Bitrate: 128 Kbps
Current Song: Swedish House Mafia - Greyhound Current DJ:
Notice: Undefined offset: 13 in C:\xampp\htdocs\stats.php on line 23
我做错了什么，还有其他方法可以做到这一点，因为fsockopen被大多数主机阻止。
