Introduction

Providing some functions for analyzing RSS document

Fegg\Tool\RSS loads an RSS 1.0 (RDF) or RSS 2.0 feed and returns its entries as arrays.

How to use

Import Fegg\Tool\RSS and create it with new, passing the feed URL.

Controller

<?php
namespace Site\Controller;

defined('FEGG_CORE_DIR') || exit;

use Fegg\Tool\RSS;

class Index extends Controller
{
    public function index()
    {
        $rss = new RSS('https://example.com/feed');
        $this->page['posts'] = $rss->fetchAll(10);

        $this->displayPage('index');
    }
}

Entry data

Each entry returned by RSS::fetch and RSS::fetchAll is an array with these keys.

Key	Data type	Remarks
title	string	Title
pubDate	string	Date as written in the feed (pubDate, or dc:date for RSS 1.0)
datetime	DateTime	pubDate as a DateTime object
link	string	Link URL
description	string	Description (HTML entities decoded)
content	string	content:encoded (HTML entities decoded)
author	string	dc:creator
category	array	Category names (category, or dc:subject for RSS 1.0)
tag	array	Always an empty array (not implemented)

メモ

• Entries whose title contains PR: (advertisements) are skipped.
• Atom feeds are not supported: no entry is returned.
• The feed is loaded with simplexml_load_file() in the constructor. A feed that cannot be loaded is not handled, so check the URL beforehand when it may be unavailable.
