Atom feed generator

This library is an Atom feed generator, PHP 7.1+, fully typed (PHPStan level 7, 100% code coverage). Follows W3C standard
(RFC 4287).

Installing

Install via Composer:

composer require ddebin/atom-generator

Example

<?php
include_once 'vendor/autoload.php';
$entry = new AtomGenerator\Entry();
$entry->setTitle('Post', 'text');
$entry->setId('tag:id');
$entry->setContent('Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.', 'text');
$entry->setUpdatedDateTime(new DateTime('2019-05-04T21:00:40Z'));
$feed = new AtomGenerator\Feed();
$feed->setTitle('Blog');
$feed->setUpdatedDateTime(new DateTime('now'));
$feed->addEntry($entry);
assert(AtomGenerator\Feed::validate($feed->getDocument()));
echo $feed->saveXML();

Validation

A validation tool is included with static method Feed::validate. It uses a Relax NG schema coming from https://validator.w3.org/feed/docs/rfc4287.html#schema (inspired by https://cweiske.de/tagebuch/atom-validation.htm).
