[PHP] Cannot get cURL to send Client-ID

If you can, post what you have right now in terms of code.

The Client ID blog has this as an example which is PHP w/ a cURL call:

<?php
 $channelsApi = 'https://api.twitch.tv/kraken/channels/';
 $channelName = 'twitch';
 $clientId = 'axjhfp777tflhy0yjb5sftsil';
 $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);
?>
