Answer by jcaron for Display text after empty RSS feed

When you call RSS_Display, instead of displaying it immediately, store its return value in a variable. Then you can test whether it's an empty string (nothing to display) or not, and act accordingly:

$rss = RSS_Display($url, 3, false, true);if ($rss == ''){    // nothing shown, do whatever you want}else{    // something to display    echo $rss;    // you can add other stuff here}
