how to get only specific variable value from json response(facebook response) - php

Question

I want only a specific value(say "name") from my generated output. I used this code
var_dump($request_object_details); to generate the below output.
What output I am getting:-
array(6) { ["id"]=> string(26) "514484461930096_1446926141" ["application"]=> array(2) { ["name"]=> string(18) "Pocket Financetest" ["id"]=> string(15) "270339389736782" } ["to"]=> array(2) { ["name"]=> string(12) "Prince Singh" ["id"]=> string(10) "1446926141" } ["from"]=> array(2) { ["name"]=> string(14) "Ashutosh Singh" ["id"]=> string(15) "100003645579131" } ["message"]=> string(16) "My Great Request" ["created_time"]=> string(24) "2013-01-17T03:45:36+0000" }
I used the below code to get the above output:
<?php
require_once('phps/fbsdk/src/facebook.php');
$config = array
(
'appId' => '270339389736782',
'secret' => '667e1795cc1f308f312d49d6b1c17cb8',
);
$facebook = new Facebook($config);
//get the request ids from the query parameter
$request_ids = explode(',', $_REQUEST['request_ids']);
//build the full_request_id from request_id and user_id
function build_full_request_id($request_id, $user_id) {
return $request_id . '_' . $user_id;
}
//for each request_id, build the full_request_id and delete request
foreach ($request_ids as $request_id)
{
$uid = $facebook->getUser();
$full_request_id = build_full_request_id($request_id, $uid);
$request_object_details = $facebook->api("/$full_request_id");
var_dump($request_object_details);//This is giving me the output
try {
$delete_success = $facebook->api("/$full_request_id",'DELETE');
if ($delete_success) {
echo "Successfully deleted " . $full_request_id;}
else {
echo "Delete failed".$full_request_id;}
}
catch (FacebookApiException $e) {
echo "error=".$e;}
}
?>

Your question is not clear but still I am posting some sort of code for you.
Use json_decode
Do like this : It will return object
$obj = json_decode($request_object_details);
$result= $obj->id;
OR
You can use json_decode and convert it into the array:
$request_object_details = $facebook->api("/$full_request_id");
$result=json_decode($request_object_details, true);
The second parameter will make decoded json string into an associative arrays.
Now you can directly use :
echo $result['id'];
echo $result['application'];
and so on...
Hope it'll help you.
