Use PHP to show Icecast2 statistics - php

Question

I have some trouble viewing statistics (viewers, current song playing etc) with PHP and I can't find any information how to do this.
There is a couple of XLS files included with Icecast2 and I could include this files with PHP to my site but I wan't to update the DIV that the include is in every 5 seconds and that won't work with XLS files.
Thanks!

Hi there and thanks for the code.
I made a class from it and added some checks so it doesn't complain when the server is offline.
Since I took it from here I will share the class back:
<?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;
}
}
?>

By using this code I've got it working:
<?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];
?>

Please take a look at my answer over here why it is a very bad idea to use this script.
tl;dr: You should not parse the Icecast HTML status page.
