Keep Coding

I'm actually new to the Api world, i'm working on an Api that fetches and sends back data using a Curl Request. On Fetch the information below is passed
{"posts":{"userinfo":{"fullname":"Precious Tom","user_name":"Kendrick","email":"tomprezine#gmail.com","gender":"Male","country":"Nigeria","city":"Port Harcourt","state":"Rivers","year":"1997","month":"9","day":"6"}}}
content type: text/html; charset=UTF-8
http code: 200
Splitting the Array seem to be my Problem, I'm sorry if this question hs been asked before, but please, i need your help.
Thanks.
For More Info, Here is my Curl Request
<?php
session_start();
# data to be sent
$data = array(
'public_key' => 'pk_test_3gc9ffb0hccggf5f3b4e258da848343dff4ae900',
'app_name' => 'Circlepanda',
'app_id' => '2147483647'
);
$curl = curl_init();
# you can also set the url you wanna communicate with by setting
# $curl = curl_init('http://localhost/circlepanda');
# We post Data
curl_setopt($curl, CURLOPT_POST, 1);
# Set the url path we want to call
curl_setopt($curl, CURLOPT_URL, 'http://localhost:8888/circlepanda/api/userinfo');
# Make it so the data coming back is put into a string
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
# You can also bunch the above commands into an array if you choose using: curl_setopt_array
# Send the request
$result = curl_exec($curl);
# Get some cURL session information back
$info = curl_getinfo($curl);
echo '<br> content type: ' . $info['content_type'] . '<br>';echo 'http code: ' . $info['http_code'] . '<br>';
# Free up the resources $curl is using
curl_close($curl);
?>
I'll be passing a Variable not a direct Array.
Tried Direct arrays your code worked fine, burr on passing a variable, it stopped working...

$city_names = json_decode('{"posts":{"userinfo":{"fullname":"Precious Tom","user_name":"Kendrick","email":"tomprezine#gmail.com","gender":"Male","country":"Nigeria","city":"Port Harcourt","state":"Rivers","year":"1997","month":"9","day":"6"}}}', true);
print_r($city_names);
ans

(
[posts] => Array

)
$city_names = json_decode($json, true);
print $arr['posts']['userinfo']['fullname'];

You've 2 options:
1 - Convert json to an object using:
$obj = json_decode($json);
print $obj->posts->userinfo->fullname;
2 - convert json to an array using:
$arr = json_decode($json, true);
print $arr['posts']['userinfo']['fullname'];
