php - I get NULL retrieving JSON from especific website -

-

i want retrieve json data here:

{      "input_address": "1bee32k9fxvrnbneukwdym26vz4gsggqzg",     "callback_url": "http://example.com",     "fee_percent": 1.5,     "destination": "12za1i1zhytcehwbg8yjb72beegqveumdt"  }

... if put on browser you'll see json data correctly formatted. no problem there.

however, when try retrieve data php using standard script:

<?php $url = 'https://blockchain.info/api/receive?method=create&format=plain&anonymous=true&address=12za1i1zhytcehwbg8yjb72beegqveumdt&callback=http%3a%2f%2fexample.com'; $json = file_get_contents($url); $data = json_decode($json); var_dump($data); echo 'url: '.$url; ?>

... no data; var_dump writes "null" (you can test previous code @ http://bitstamina.com/theamazinghat/thehat.php). , yet, if try other url returns json data code works perfectly.

what doing wrong? must either stupid mistake on part, or site blockchain.info has blocked site making requests.

i believe due cross domain mismatch. changing page https or call using http. http://blockchain.info/api/receive?method=create&format=plain&anonymous=true&address=12za1i1zhytcehwbg8yjb72beegqveumdt&callback=http%3a%2f%2fexample.com

this works.
