@SPETSDev What isn’t working? The code you posted works just fine. You simply need to decode and then output what you already have. For example:
<?php
$channelsApi = 'https://api.twitch.tv/kraken/channels/';
$channelName = 'somechannel';
$clientId = 'myClientID';
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_HTTPHEADER => array(
'Client-ID: ' . $clientId
),
CURLOPT_RETURNTRANSFER => true,
CURLOPT_URL => $channelsApi . $channelName
));
$response = curl_exec($ch);
curl_close($ch);
$json = json_decode($response, true);
echo $json['display_name'];
?>
