    $postData = array('longUrl' => $longUrl);
    $jsonData = json_encode($postData);

    $curlObj = curl_init(); 
    curl_setopt($curlObj, CURLOPT_URL, 'https://www.googleapis.com/urlshortener/v1/url?key=yourappkey');
    curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curlObj, CURLOPT_HEADER, 0);
    curl_setopt($curlObj, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($curlObj, CURLOPT_POST, 1);
    curl_setopt($curlObj, CURLOPT_POSTFIELDS, $jsonData);

    //5
    $response = curl_exec($curlObj);

    $json = json_decode($response);
//       echo "

//    print_r($json);exit;

    curl_close($curlObj);

    if(isset($json->error)){
        echo $json->error->message;
    }else{

    }
