Question

I am successfully parsing an RSS feed with PHP, but want to return a message when the feed is empty. I have included the
PHP File here to show you what I want to achieve.

I’m looking for it to break or stop executing, but print a message and stop at the point highlighted.

Thanks for your assistance.

DOMNode::getElementsByTagName returns a DOMNodeList object. To test if it’s empty use its $length member.

if ($x->length == 0) {
    exit('etc.');
}
