PHP pull and display values from API url - php

Question

If I use the following:
$homepage = file_get_contents('http://www.website.com/api/v1/members/102210');
echo $homepage;
The data is displayed as follows:
{"user":{"profile":{"Id":{"Label":"User Id","Value":102210},"User":{"Label":"User Name","Value":"tom"}
I tried the following that I discovered on here in another post but the page remains blank other than User:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "http://www.website.com/api/v1/members/102210",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"cache-control: no-cache"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
$response = json_decode($response, true); //because of true, it's in an array
echo 'User: '. $response['User']['User Name'];

You're misinterpreting the JSON data. There is no User key in the root of the json object and there is no User Name key inside of that either. When you visualize the JSON, this is what it looks like:
What you seem to be looking for is:
echo 'User: ' . $response['user']['profile']['User']['Value'];
I'm not sure why you'd switch to cURL if the file_get_content method works for you. You should be able to simply do this:
$homepage = file_get_contents('http://www.website.com/api/v1/members/102210');
$response = json_decode($homepage, true);
echo 'User: ' . $response['user']['profile']['User']['Value'];
