php - PHP を使用して Icecast2 の統計情報を表示する

Question

PHP を使用して統計 (視聴者、現在再生中の曲など) を表示する際に問題があり、これを行う方法に関する情報が見つかりません。

Icecast2 には XLS ファイルがいくつか含まれており、このファイルを PHP で自分のサイトに含めることができますが、5 秒ごとに含まれている DIV を更新したくなく、XLS ファイルでは機能しません。

ありがとう！

こんにちは、コードをありがとう。それからクラスを作成し、サーバーがオフラインのときに文句を言わないようにいくつかのチェックを追加しました。ここから取ったので、クラスを共有します。

<?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

このコードを使用することで、私はそれを機能させました：

<?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];

?>

このスクリプトを使用することが非常に悪い考えである理由については、こちらの私の回答をご覧ください。
