 {        $post_data = array(            'auth-userid' => 611510,            'api-key' => 'api',            'domain-name'=>array('domain1','domain2'),            'tlds' => 'com',        );        $result=http_build_query($post_data);              var_dump($result);    }

$post_data = array(            'auth-userid' => 611510,            'api-key' => 'api',            'domain-name'=>array('domain1','domain2'),            'tlds' => 'com',        );        $result=http_build_query($post_data);              var_dump($result);        var_dump(urldecode($result));
