Reddit json and PHP - opening foreach() and getting values - php

Question

I am trying to read a reddit json using my account as an example.
Tried the solution above as:
$string_reddit = file_get_contents("https://www.reddit.com/user/joshfolgado/about.json");
$json = json_decode($string_reddit, true);
$children = $json['data'];
foreach ($children as $child){
$linkkarma = $child['data']['link_karma'];
}
Also tried:
foreach ($json->data as $mydata){
$values["Latest_Karma"] = $mydata['link_karma'];
}
Also tried:
$opts = array(
'http'=>array(
'method'=>"GET",
'header'=>"User-Agent: reddiant api script\r\n"
));
$context = stream_context_create($opts);
$url = "http://www.reddit.com/user/joshfolgado/about.json";
$json = file_get_contents($url, false, $context);
$result = json_decode($json, true);
foreach ($result as $child){
$values['Latest_Karma'] = $child['data']['link_karma'];
}
Spent a couple of hours trying do get the values for any of the items inside the "data" array, havent been able to get any.
What am I doing wrong? What am I missing?
Any help is appreciated.
Thanks

$string_reddit = file_get_contents("http://www.reddit.com/user/joshfolgado/about.json");
$json = json_decode($string_reddit, true);
$children = $json['data'];
foreach ($children as $child){
$link_karma= $child['link_karma'];
}

Answer 2

A slight modification to pee2pee's post (His returned an undefined index error for me)
$string_reddit = file_get_contents("http://www.reddit.com/user/joshfolgado/about.json");
$json = json_decode($string_reddit, true);
$children = $json['data'];
$user = [];
foreach ($children as $key => $value)
{
$user[$key] = $value;
}
echo $user['name']; //Now you can use the $user array to access all the properties!
This works for me ->
