Simple RSS reader in php with continuous scrolling

Question

I already made a simple RSS reader, but it only gets me like 25 articles. How do I make it to work like feedly.com or digg.com, so that it retrieves me many more feeds, and not only 25?

The php code I have:

$rss = simplexml_load_file('http://www.elespectador.com/rss.xml');

I already know how to retrieve the title, description, etc. of each item.

Answer 1

Pagination in feeds is arbitrary and you'll have trouble finding a consistent pattern. You should store any data so that now you have 25 elements, but when new ones are added, you keep adding more and more. Another solution is to use the data from a service like Superfeedr (I created it!) which stores past content for milions of feeds.
