class FeedFinder is a utility class that FeedWordPress uses to find the best options for feed URLs associated with a given URL. If the content at the given URL appears a feed, then FeedFinder will return the URL itself. If the content at the given URL appears to be a human-readable web page, FeedFinder will attempt to use standard feed auto-discovery techniques and return the URLs of any feeds that appear to be associated with the page.

Example

$ff = new FeedFinder($lookupUrl);



$foundFeeds = $ff->find();
if (count($foundFeeds) > 0) :
    foreach ($foundFeeds as $url) :



        // Make sure this is a working URL not an HTTP error
        if (!is_wp_error($url)) :
            /* Do something with the URL in $url . . . */



            // The first url ($foundFeeds[0]) is likely to be the best candidate
            // After we've made use of the first available, get out of this loop.
            break;
        endif;
    endforeach;
endif;
