Json and printing the resulting array into variables

Question

I am using cURL to get json information from a site that pulls a random tumblr picture from a list of sources and I am interested of putting the json data retrieved into php variables so I can call for example, just the image url

$url = "http://someurl.com";
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($ch, CURLOPT_URL,$url);

            $a = curl_exec($ch);
                    $json = var_dump(json_decode($a, true));

I get:

array(3) {
  'image' =>
  array(1) {
    [0] =>
    string(62) "http://picture.jpg"
  }
  'source' =>
  string(31) "http://source.tumblr.com"
  'page' =>
  string(9) "/page/164"
}

What would I now do in order to just print the url for the image?

I have tried

$url = $json["image"][0];

and then calling $url, but it gives me nothing in return. What I am doing wrong?

I have never worked with json before so I am at a loss here, any help is appreciated!

try $json = json_decode($a, true); can you show full example you have — Rakesh Sharma

according to code looks:-

try change

$json = var_dump(json_decode($a, true));

to

$json = json_decode($a, true);

Thanks! That worked out just fine. If you don't mind, do explain why it works without var_dump. I am somewhat still of a newbie to php and I'd love to learn more.

@SaadChaudhry, There was apparently a 5 minute timer before I could mark it as answered, done now! =) RakeshSharma, Appears I was at a loss on how var_dump works, was using it to print the structure of the array. Thanks for the answer!
