        'published'   => date('Y-m-d H:i:s')
    ]
];

$feed = new Writer($headers, $items);
$feed->render();

渲染为 RSS 源

<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0"
    xmlns:content="http://purl.org/rss/1.0/modules/content/"
    xmlns:wfw="http://wellformedweb.org/CommentAPI/">
    <channel>
        <published>Tue, 21 Jul 2015 18:09:08 -0500</published>
        <author>Test Author</author>
        <item>
            <title>Some Item #1</title>
            <link>http://www.popphp.org/</link>
            <description>This is the description of item #1</description>
            <published>Tue, 21 Jul 2015 18:09:08 -0500</published>
        </item>
        <item>
            <title>Some Item #2</title>
            <link>http://popcorn.popphp.org/</link>
            <description>This is the description of item #2</description>
            <published>Tue, 21 Jul 2015 18:09:08 -0500</published>
        </item>
    </channel>
</rss>

或者，渲染为 Atom 源

$feed = new Writer($headers, $items);
$feed->setAtom();
$feed->render();

<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom" xml:lang="en">
    <published>Tue, 21 Jul 2015 18:10:39 -0500</published>
    <author>
        <name>Test Author</name>
    </author>
    <entry>
        <title>Some Item #1</title>
        <link href="http://www.popphp.org/" />
        <description>This is the description of item #1</description>
        <published>Tue, 21 Jul 2015 18:10:39 -0500</published>
    </entry>
    <entry>
        <title>Some Item #2</title>
        <link href="http://popcorn.popphp.org/" />
        <description>This is the description of item #2</description>
        <published>Tue, 21 Jul 2015 18:10:39 -0500</published>
    </entry>
</feed>

解析源

如果源是 RSS 源

use Pop\Feed\Reader;
use Pop\Feed\Format\Rss;

$feed = new Reader(new Rss('http://www.domain.com/rss'));

foreach ($feed->items as $item) {
    print_r($item);
}

如果源是 Atom 源

use Pop\Feed\Reader;
use Pop\Feed\Format\Atom;

$feed = new Reader(new Atom('http://www.domain.com/feed'));

foreach ($feed->entries as $entry) {
    print_r($entry);
}
