Serialized PHP Response Format

PHP has a built-in serialized data structure format, using the serialize() and unserialize() functions.

To return an API response in PHP serialized format, send a parameter "format" in the request with a value of "php_serial".

The returned data structures match the JSON response structures - please read the JSON documentation for further details.

To perform a very simple request in PHP 5, your code might look like this:





#



# build the API URL to call



#







$params = array(



'api_key' => '81e7e11aeac57ac668609d316f6388ce',



'method' => 'flickr.photos.getInfo',



'photo_id' => '251875545',



'format' => 'php_serial',



);







$encoded_params = array();







foreach ($params as $k => $v){







$encoded_params[] = urlencode($k).'='.urlencode($v);



}











#



# call the API and decode the response



#







$url = "http://http://www.zjjv.com///services/rest/?".implode('&', $encoded_params);







$rsp = file_get_contents($url);







$rsp_obj = unserialize($rsp);











#



# display the photo title (or an error if it failed)



#







if ($rsp_obj['stat'] == 'ok'){







$photo_title = $rsp_obj['photo']['title']['_content'];







echo "Title is $photo_title!";



}else{







echo "Call failed!";



}
