How to get data from an array inside json data php - php

Question

I have the following array of json data. When I try to loop using a for each, php gives me the error "Object of class stdClass could not be converted to string". I want to access the nameserver in the authns array, and the soa array. How do I go about doing that?
stdClass Object (
[error] =>
[domain] => whoisdoma.net
[ip_address] => 108.162.199.120
[authns] => stdClass Object (
[nameserver] => uma.ns.cloudflare.com
[ip] => 173.245.58.146
[location] => San Francisco
)
[soa] => stdClass Object (
[nameserver] => tom.ns.cloudflare.com
[email] => dns.cloudflare.com
[serial] => 2015505396
[refresh] => 10000
[retry] => 2400
[expiry] => 604800
[minimum] => 3600
)
)
This is the code I'm using to get the data:
<?php
$domain = $_GET['domain'];
//set the url
$url = "http://api.site.ga/v1/dns/lookup?domain=".$domain;
//start a curl session
$ch = curl_init();
$timeout = 5;
//set curl options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
//get the data
$data = curl_exec($ch);
//decode the data
$jsonData = json_decode($data);
//close the curl session
curl_close($ch);
?>
This is the for each loop I'm using
<?php
foreach($jsonData->authns as $authns)
{
echo $authns->nameserver;
}
?>

Answer 1

You need to decode the json object using an associative array.
Here is an exmaple:
$data = json_decode(file_get_contents('http://api.domain.com/call'), true);
$data is now an associative array.

Answer 2

You are looping through authns while it is an object by itself. So your nameserver which you want is actually $authns in its first iteration.
Just access it like $jsonData->authns->nameserver
try this for yourself
foreach($jsonData->authns as $authns)
{
echo $authns;
}
