Getting images from Instagram, always null - php

Question

I develop a small script on localhost (WAMP server, CURL enabled) to retrieve images from Instagram. Based on this script: see tutorial I have also set up the variables on Instagram. I'm not sure what is wrong more specifically or how to solve it (probably with authentication).
USER ID
CLIENT ID
CLIENT SECRET
WEBSITE URL
REDIRECT URI
This is my user
http://instagram.com/krondorl
function fetchData($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$result = fetchData("https://api.instagram.com/v1/users/280766222/media/recent/?access_token=df04c6989eaf4490bdac1f82554182bb");
$result = json_decode($result);
var_dump($result);

Try the code below which works for me. Make sure your URL is correct.
$json_url ='https://api.instagram.com/v1/users/280766222/media/recent/?access_token=df04c6989eaf4490bdac1f82554182bb';
// Initializing curl
$ch = curl_init( $json_url );
// Configuring curl options
$options = array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array('Content-type: application/json')
);
// Setting curl options
curl_setopt_array( $ch, $options );
// Getting results
$results = curl_exec($ch); // Getting jSON result string
$json_decoded = json_decode($results);
By the way I check your URL which happens to be incorrect and give me the below error.
{"meta":{"error_type":"OAuthAccessTokenException","code":400,"error_message":"The \"access_token\" provided is invalid."}}
Before you trying the code, try the URL on the browser and see whether the URL is correct.
