从PHP文件中提取统计数据

问题描述

我有一个jQuery播放器，其顶部有一个统计栏，可从远程xml文件中提取信息.

I have a jQuery player with a stats bar on top that draw information from a remote xml file.

我正在尝试对其进行修改，以从php文件中读取统计信息.

I'm trying to modify it to read stats from a php file.

该php文件从远程服务器中的xspf文件提取统计信息.

That php file draw the stats from a xspf file in the remote server.

我该如何使用以下代码来做到这一点:

How do i go about doing that with the following code:

更新代码:

php文件:

<?php
header('Content-Type:text/xml');

$xml = simplexml_load_file("http://**.**.**.**:8000/live.xspf");

echo '<?xml version="1.0" encoding="UTF-8"?><tracks>';
foreach ($xml->trackList->track as $data) {
    $radio = $data->location;
    $song  = $data->title;
    $info = $data->listeners;
    echo '<track>
            <title>'.$song.'</title>
            <listeners>'.$info.'</listeners>
            <location>'.$radio.'</location>
          </track>';
}
echo '</tracks>';
?>

jQuery代码:

    function getCurrentTrack(){
$.get('/player/readerPlayer.php'), function (){
    $track = $(data).find('track');
    $track.each(function (){
        $this = $(this);
        var title = $this.find('title').text();
        var listenersn = $this.find('listeners').text();
        $('.listeners span').html(listenersn);
        setTimeout('getCurrentTrack()', 65000);
    });
}, 'xml'};

推荐答案

您只需要从PHP文件中输出XML.

You simply need to output XML from your PHP file.

header('Content-Type:text/xml');
echo '<?xml version="1.0" encoding="UTF-8"?><tracks>';
foreach ($xml->trackList->track as $data) {
    $radio = $data->location;
    $song  = $data->title;
    $info = $data->listeners;
    echo '<track>
            <title>'.$song.'</title>
            <listeners>'.$info.'</listeners>
            <location>'.$radio.'</location>
          </track>';
}
echo '</tracks>';

您将需要稍微调整一下js，以便首先获取跟踪对象.

You'll want to adjust the js a little bit to get the track objects first though.

function getCurrentTrack(){
    $.get('/player/readerPlayer.php'), function (){
        $track = $(data).find('track');
        $track.each(function (){
            $this = $(this);
            var title = $this.find('title').text();
            var listenersn = $this.find('listeners').text();
            $('.listeners span').html(listenersn);
            setTimeout('getCurrentTrack()', 65000);
        });
    }, 'xml');
}
