How to get the Max Viewers of an Game out by Streamers, and specify wich one?

API

Should that not echo game id?

$gameName = htmlspecialchars($_POST['name1']);
 $getGameID = 'https://api.twitch.tv/helix/games?game_name=';
 $clientId = 'xxx';
 $ch = curl_init();
 $apiVers = '&api_version=5';
 
 curl_setopt_array($ch2, array(
    CURLOPT_HTTPHEADER => array(
       'Client-ID: ' . $clientId
    ),
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_URL => $getGameID . $gameName . $apiVers
 ));

 $response2 = curl_exec($ch2);

$resp = json_decode($response2);
$gameID = $resp->data[0]->game_id;
