PHP object holding XML data

Question

How to check whether any data is returned in Object $twitter_xml for query abc or its empty?

Following is the code:

 $url="http://search.twitter.com/search.rss?q=abc";
 $twitter_xml = simplexml_load_file($url);

You will always get an XML response. What element are you looking for in it? — Pekka

This will give you a count of items:

count($twitter_xml->channel->item);

I'm not sure what Twitter returns, but you should be able to do an isset() on a value you expect to exist.

E.g.

if(isset($twitter_xml->name))
{
    // XML has a 'name' element
}
else
{
    // No 'name' element
}
