Leer url

[sagdec]

Que tal, quisiera saber de que manera puedo acceder a los datos que me arroja la siguiente direccion url:

Código PHP:

$url='http://www.mapquestapi.com/geocoding/v1/reverse?key='.$llave.'&callback=renderReverse&location=28.646949,-106.0934118';
 
$ch = curl_init($url);  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 
$result = curl_exec ($ch);
 
print_r($result);
 
curl_close($ch);
 

El resultado que se imprime es el siguiente:

renderReverse({"info":{"statuscode":0,"copyright": {"text":"\u00A9 2015 MapQuest, Inc.","imageUrl":"http://api.mqcdn.com/res/mqlogo.gif","imageAltText":"\u00A9 2015 MapQuest, Inc."},"messages":[]},"options":{"maxResults":1,"thumbMaps":true,"igno reLatLngInput":false},"results":[{"providedLocation":{"latLng":{"lat":28.646949,"ln g":-106.0934118}},"locations":[{"street":"209 Calle L\u00E1zaro de Baigorri","adminArea6":"","adminArea6Type":"Neighb orhood","adminArea5":"Chihuahua","adminArea5Type": "City","adminArea4":"Chihuahua","adminArea4Type":" County","adminArea3":"CH","adminArea3Type":"State" ,"adminArea1":"MX","adminArea1Type":"Country","pos talCode":"31203","geocodeQualityCode":"P1AAA","geo codeQuality":"POINT","dragPoint":false,"sideOfStre et":"R","linkId":"0","unknownInput":"","type":"s", "latLng":{"lat":28.646896,"lng":-106.093244},"displayLatLng":{"lat":28.646911,"lng" :-106.093333},"mapUrl":"http://www.mapquestapi.com/staticmap/v4/getmap?key=ZbpJWaXKhDaxLGZKH4h0HXVQnVWsZLWC&type=m ap&size=225,160&pois=purple-1,28.646896,-106.093244,0,0,|¢er=28.646896,-106.093244&zoom=15&rand=80197112"}]}]})

Pero no se como acceder a los elementos internos para mostrar lo que necesito que en este caso sería obtener todos lo de "locations".
