Código PHP:
<?php
require("OAuth.php");
$cc_key = "dj0yJxxxxxxxxxPTAw";
$cc_secret = "0xxxxxxxxxd";
$url = "http://yboss.yahooapis.com/ysearch/web";
$args = array();
$args["q"] = "MOZILLA";
$args["format"] = "json";
$args["market"] = "es-es";
$args["count"]=3;
$consumer = new OAuthConsumer($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_HEADER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER); //AGREGADO ESTO??
$rsp = curl_exec($ch);
$results = json_decode($rsp);
echo $results;
// OUTPUTS
echo "</br></br>VARIABLES: </br>";
echo "QUERY : ".$args["q"] ."</br>";
echo "FORMAT : ".$args["format"] ."</br>";
echo "MARKET : ".$args["market"] ."</br>";
echo "COUNT : ".$args["count"] ."</br></br>";
//echo "CONSUMER : ".$consumer ."</br></br>";
//echo "REQUEST : ".$request ."</br></br>";
echo "URL : ".$url ."</br></br>";
echo "</br></br>TRYING SHOW RESULTS:</br></br>";
echo $results["bossresponse"]["responsecode"]["results"][0]["title"][0]; //Title
echo $results["bossresponse"]["responsecode"]["results"][0]["clickurl"][0]; // Click URL
echo $results["bossresponse"]["responsecode"]["results"][0]["abstract"][0]; // Result
echo $results->bossresponse->responsecode->results[0]->title[0];
echo $results->bossresponse->responsecode->results[1]->title[1];
echo $results->bossresponse->responsecode->web->results[1]->title[1];
echo $results->responsecode->web->results[1]->title[1];
echo $results->bossresponse->web->results[1]->title[1];
echo $results->bossresponse->responsecode->results[0]->title;
echo $results->bossresponse->responsecode->results[1]->title;
