JSON PHP解析搜索API

Alright, I'm using the Blekko search API:

http://blekko.com/ws/?q=hello+%2Fjson

how would I go about parsing it ?

I have no experience of parsing JSON from PHP, so I'd appreciate a little help, and the json_decode() docs failed to explain everything for me, particularly getting the data inside RESULT. :) You know, [ and ].

Could you help pointing me in the right direction ? :)

Thank you, you're all so helpful! :)

Here's the code to access the API. You should enter your own error/unexpected results handling where i've left the comments.

$data = file_get_contents('http://blekko.com/ws/?q=hello+%2Fjson');

if(!empty($data)){

    $data = json_decode($data);

    if(!empty($data->ERROR)){

         // Error with API response.

    } else {

        $data = $data->RESULT;
        if(empty($data)){

            // No results.

        } else {

                // Uncomment the line below to see your data
                // echo '<pre>' . print_r($data) . '</pre>';

            foreach($data AS $key => $val){     
                echo $val->short_host . '<br />';
            }
        }
    }

} else {
    // Failed to retrieve data.
}
