## General Usage
```php
require 'vendor/autoload.php';
$rss = new UniversalFeedCreator();
$rss->useCached(); // use cached version if age < 1 hour
$rss->title = "PHP news";
$rss->description = "daily news from the PHP scripting world";
//optional
$rss->descriptionTruncSize = 500;
$rss->descriptionHtmlSyndicated = true;
$rss->link = "http://www.dailyphp.net/news";
$rss->syndicationURL = "http://www.dailyphp.net/" . $_SERVER["PHP_SELF"];
$image = new FeedImage();
$image->title = "dailyphp.net logo";
$image->url = "http://www.dailyphp.net/images/logo.gif";
$image->link = "http://www.dailyphp.net";
$image->description = "Feed provided by dailyphp.net. Click to visit.";
//optional
$image->descriptionTruncSize = 500;
$image->descriptionHtmlSyndicated = true;
$rss->image = $image;
// get your news items from somewhere, e.g. your database:
mysql_select_db($dbHost, $dbUser, $dbPass);
$res = mysql_query("SELECT * FROM news ORDER BY newsdate DESC");
while ($data = mysql_fetch_object($res)) {
$item = new FeedItem();
$item->title = $data->title;
$item->link = $data->url;
$item->description = $data->short;
//optional
$item->descriptionTruncSize = 500;
$item->descriptionHtmlSyndicated = true;
$item->date = $data->newsdate;
$item->source = "http://www.dailyphp.net";
$item->author = "John Doe";
$rss->addItem($item);
}
echo $rss->saveFeed("RSS1.0", "news/feed.xml");
