Display API search results with PHP

I am able to retrieve results from yahoo with my API key, using the instructions found here

Code:

<?php
require("OAuth.php");

$cc_key  = "your consumer key here";
$cc_secret = "your consumer secret here";
$url = "<http://yboss.yahooapis.com/ysearch/news>,web,images";
$args = array();
$args["q"] = "yahoo";
$args["format"] = "json";

$consumer = new OAuthConsumer($cc_key, $cc_secret);
$request = OAuthRequest::from_consumer_and_token($consumer, NULL,"GET", $url, $args);
$request->sign_request(new OAuthSignatureMethod_HMAC_SHA1(), $consumer, NULL);
$url = sprintf("%s?%s", $url, OAuthUtil::build_http_query($args));
$ch = curl_init();
$headers = array($request->to_header());
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$rsp = curl_exec($ch);
$results = json_decode($rsp);
print_r($results);
?>

However the output of results is very bizarre, for example, if I search for elephant, I get the following results (partial copy and paste):

stdClass Object ( [bossresponse] => stdClass Object ( [responsecode] => 200 [images] => stdClass Object ( [start] => 0 [count] => 35 [totalresults] => 108000 [results] => Array ( [0] => stdClass Object ( [clickurl] => http://0.tqn.com/d/goafrica/1/0/Y/Q/IMG_1592.JPG [size] => 2.2MB [format] => jpeg [height] => 2432 [refererclickurl] => http://goafrica.about.com/od/africanwildlife/ss/The-Big-5-Images-Facts-And-Information-About-Africas-Big-Five_2.htm [refererurl] => http://goafrica.about.com/od/africanwildlife/ss/The-Big-5-Images-Facts-And-Information-About-Africas-Big-Five_2.htm [title] => African Elephant - One of the "Big Five" - African Elephant Image ...

By the way, the links are not clickable in my results, even though they are above.

Please bear in mind that I am very new to php, and programming in generally. Any suggestions on how to display the results properly?

Thanks
