使用PHP解析iTunes RSS Atom？

Question

[尝试使用PHP脚本解析iTunes Atom提要。如果您访问iTunes RSS Generator，则可以生成如下所示的Atom供稿：https://rss.itunes.apple.com/api/v1/id/apple-music/new-releases/all/10/explicit.rss

如何获得这样的数据：

1. 标题1A类B类日期

2. 标题2A类B类日期

3. 标题3A类B类日期

Answer 1

您可以使用SimpleXML轻松而轻松地解析RSS feed，例如：

<?php

// Load the feed using SimpleXML
$xml = simplexml_load_file('https://rss.itunes.apple.com/api/v1/id/apple-music/new-releases/all/10/explicit.rss');

foreach ($xml->channel->item as $item) {
    // Work with each item within the RSS feed
    print_r($item);

    // $item->title
    // $item->category
    // $item->link
    // $item->guid
    // $item->description
    // $item->pubDate
}

示例控制台输出：

SimpleXMLElement Object

    [title] => Lexicon - Isyana Sarasvati
    [category] => Array
        (
            [0] => Isyana Sarasvati

Aran击败了我，但自从我写下以来，就将其发布在这里。

[如果您要避免为每个节点处理SimpleXMLElement objects。

$xml = simplexml_load_file('https://rss.itunes.apple.com/api/v1/id/apple-music/new-releases/all/10/explicit.rss');

$items = [];
foreach($xml->channel->item as $item) {
    $category = json_decode(json_encode($item->category), true);

    array_push($items, (object) [
        'title' => (string) $item->title,
        'link'  => (string) $item->link,
        'guid'  => (string) $item->guid,
        'desc'  => (string) $item->description,
        'date'  => (string) $item->pubDate,
        'category' => array_filter($category, 'is_int', ARRAY_FILTER_USE_KEY),
    ]);
}

var_dump($items[1]->category[2]);
# output: string(11) "Alternative"
