我需要绝望的帮助来获取特定频道播放的当前电视节目。我想使用这个 API http://www.webtelevideo.com/api/来获取程序名称。我发现这个页面抓取了所有意大利电视频道的所有节目，但我只想显示指定频道当前播放的节目。因此，没有国家数据、语言、评级等……只有在查看网页时正在播放的电视节目的名称。我试着去http://www.webtelevideo.com/api/getSchedule.php?channel_id=350 （例如）但我只想让当前程序出现，只有一个字符串。我知道在网上和 stackoverflow 上有很多关于 API 和 cURL 的帖子，但我是这类东西的菜鸟，我真的需要你的帮助。非常感谢提前

<?php $guide = get_post_meta($post->ID, '_wpb_in_onda', true); ?>

<?php
function GetChanels()
{
    return json_decode(file_get_contents("http://www.webtelevideo.com/api/getSchedule.php"),true);
}
function GetProgramsOnChanel($ChanName)
{
    foreach(GetChanels() as $Chanel)
    {
        {
            return $Chanel["Program"];
        }
    }
    return Array("name"=>"none");
}
function GetCurrentProgramOnChanel($ChanName)
{
    foreach(GetProgramsOnChanel($ChanName) as $Program)
    {
        $Title = $Program["title"];
        $start = strtotime($Program["ProgramSchedule"]["start"]);
        $end = strtotime($Program["ProgramSchedule"]["stop"]);
        $Current = ($start < strtotime("now +1 hour") and strtotime("now +1 hour") < $end); 
        if($Current)
        {
            return $Program;
        }
    }
    return Array("title"=>"none");
}

foreach(GetChanels() as $Chan)
$CurrentProgram = GetCurrentProgramOnChanel(" . $guide . ");
echo "Ora è in onda: " . $CurrentProgram["title"] . ". ";
echo "Termina alle: " . $CurrentProgram["ProgramSchedule"]["stop"] . " (ora italiana) <br>";
?>

以下 php 为您提供来自 api 的数据。您可以更改它以适合您的需求 =)

<?php
    function GetChanels()
    {
        return json_decode(file_get_contents("http://www.webtelevideo.com/api/getSchedule.php"),true);
    }
    function GetProgramsOnChanel($ChanName)
    {
        foreach(GetChanels() as $Chanel)
        {
            if($Chanel["name"] == $ChanName)
            {
                return $Chanel["Program"];
            }
        }
        return Array("name"=>"none");
    }
    function GetCurrentProgramOnChanel($ChanName)
    {
        foreach(GetProgramsOnChanel($ChanName) as $Program)
        {
            $Title = $Program["title"];
            $start = strtotime($Program["ProgramSchedule"]["start"]);
            $end = strtotime($Program["ProgramSchedule"]["stop"]);
            $Current = ($start < strtotime("now +1 hour") and strtotime("now +1 hour") < $end); // + 1 hour is for timezone adjustment
            if($Current)

            }
