使用 PHP 显示 Icecast2 统计数据

Question

我在使用 PHP 查看统计数据（观众、当前播放的歌曲等）时遇到一些问题，并且找不到任何如何执行此操作的信息。

Icecast2 中包含几个 XLS 文件，我可以使用 PHP 将此文件包含到我的网站中，但我不想更新包含每 5 秒一次的 DIV，并且不适用于 XLS 文件。

谢谢！

您好，感谢您的代码。
我用它创建了一个类并添加了一些检查，这样当服务器离线时它就不会抱怨。
因为我从这里拿走它，所以我将分享该课程：

<?php

class IceCast {
    var $server = "http://localhost:8000";
    var $stats_file = "/status.xsl";
    var $radio_info=array();

    function __construct() {
        //build array to store our radio stats for later use        
        $this->radio_info['server'] = $this->server;
        $this->radio_info['title'] = 'Offline';
        $this->radio_info['description'] = 'Radio offline';
        $this->radio_info['content_type'] = '';
        $this->radio_info['mount_start'] = '';
        $this->radio_info['bit_rate'] = '';
        $this->radio_info['listeners'] = '';
        $this->radio_info['most_listeners'] = '';
        $this->radio_info['genre'] = '';
        $this->radio_info['url'] = '';
        $this->radio_info['now_playing'] = array();
        $this->radio_info['now_playing']['artist'] = 'Unknown';
        $this->radio_info['now_playing']['track'] = 'Unknown';
    }

    function setUrl($url) {
        $this->server=$url;
        $this->radio_info['server'] = $this->server;
    }

    private function fetch() {
        //create a new curl resource
        $ch = curl_init();

        //set url
        curl_setopt($ch,CURLOPT_URL,$this->server.$this->stats_file);

        //return as a string
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

        //$output = our stauts.xsl file
        $output = curl_exec($ch);

        //close curl resource to free up system resources
        curl_close($ch);

        return $output;
    }

    function getStatus() {
        $output=$this->fetch();

        //loop through $ouput and sort into our different arrays
        $temp_array = array();

        $search_for = "<td\s[^>]*class=\"streamdata\">(.*)<\/td>";
        $search_td = array('<td class="streamdata">','</td>');


        if(preg_match_all("/$search_for/siU",$output,$matches)) {
           foreach($matches[0] as $match) {
              $to_push = str_replace($search_td,'',$match);
              $to_push = trim($to_push);
              array_push($temp_array,$to_push);
           }
        }

        if(count($temp_array)) {
            //sort our temp array into our ral array
            $this->radio_info['title'] = $temp_array[0];
            $this->radio_info['description'] = $temp_array[1];
            $this->radio_info['content_type'] = $temp_array[2];
            $this->radio_info['mount_start'] = $temp_array[3];
            $this->radio_info['bit_rate'] = $temp_array[4];
            $this->radio_info['listeners'] = $temp_array[5];
            $this->radio_info['most_listeners'] = $temp_array[6];
            $this->radio_info['genre'] = $temp_array[7];
            $this->radio_info['url'] = $temp_array[8];

            if(isset($temp_array[9])) {
                $x = explode(" - ",$temp_array[9]);
                $this->radio_info['now_playing']['artist'] = $x[0];
                $this->radio_info['now_playing']['track'] = $x[1];
            }
        }
        return $this->radio_info;
        }

}
?>

Answer 2

通过使用这段代码，我已经让它工作了：

<?php

/*
 * SCRIPT CONFIGURATIONS
*/
$SERVER = 'http://myserver.com:8000'; //URL TO YOUR ICECAST SERVER
$STATS_FILE = '/status.xsl'; //PATH TO STATUS.XSL PAGE YOU CAN SEE IN YOUR BROWSER (LEAVE BLANK UNLESS DIFFERENT)

///////////////////// END OF CONFIGURATION --- DO NOT EDIT BELOW THIS LINE \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

//create a new curl resource
$ch = curl_init();

//set url
curl_setopt($ch,CURLOPT_URL,$SERVER.$STATS_FILE);

//return as a string
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

//$output = our stauts.xsl file
$output = curl_exec($ch);

//close curl resource to free up system resources
curl_close($ch);

//build array to store our radio stats for later use
$radio_info = array();
$radio_info['server'] = $SERVER;
$radio_info['title'] = '';
$radio_info['description'] = '';
$radio_info['content_type'] = '';
$radio_info['mount_start'] = '';
$radio_info['bit_rate'] = '';
$radio_info['listeners'] = '';
$radio_info['most_listeners'] = '';
$radio_info['genre'] = '';
$radio_info['url'] = '';
$radio_info['now_playing'] = array();
   $radio_info['now_playing']['artist'] = '';
   $radio_info['now_playing']['track'] = '';

//loop through $ouput and sort into our different arrays
$temp_array = array();

$search_for = "<td\s[^>]*class=\"streamdata\">(.*)<\/td>";
$search_td = array('<td class="streamdata">','</td>');

if(preg_match_all("/$search_for/siU",$output,$matches)) {
   foreach($matches[0] as $match) {
      $to_push = str_replace($search_td,'',$match);
      $to_push = trim($to_push);
      array_push($temp_array,$to_push);
   }
}

//sort our temp array into our ral array
$radio_info['title'] = $temp_array[0];
$radio_info['description'] = $temp_array[1];
$radio_info['content_type'] = $temp_array[2];
$radio_info['mount_start'] = $temp_array[3];
$radio_info['bit_rate'] = $temp_array[4];
$radio_info['listeners'] = $temp_array[5];
$radio_info['most_listeners'] = $temp_array[6];
$radio_info['genre'] = $temp_array[7];
$radio_info['url'] = $temp_array[8];

$x = explode(" - ",$temp_array[9]);
$radio_info['now_playing']['artist'] = $x[0];
$radio_info['now_playing']['track'] = $x[1];

?>

请查看我的回答这里 为什么使用这个脚本是一个非常糟糕的主意。
tl;dr：您不应该解析 Icecast HTML 状态页面。
