Question

Could someone point me to a guide or some information on building a simple online rss reader. I’ve only been able to find guides on making rss feeds for your own site. Thanks

Answer 1

Should it read contents from only one feed?

You might want to use simpleXML in case, here is a minimal example:

$url = $url_of_the_feed_in_question;
foreach(simplexml_load_file($url)->entry as $entry) {
  echo '<h2>'.$entry->title.'<h2>'.entry->content; 
}

For a more complete guide, take a look here.

(BTW, try googling for “parser” instead of “reader”)
