This for print and use API:

$cho = curl_init('https://id.twitch.tv/oauth2/token');
curl_setopt($cho, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($cho, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($cho, CURLOPT_POST, 1);
$fields = array(
    'client_id' => 'c533u8ntdp29h42xxzwfe0pf5v66dm',
    'client_secret' => 'XXXXXXXXXXXXXXXXXXXXXXXXXXXX',
    'grant_type' => 'client_credentials'
);
curl_setopt($cho, CURLOPT_POSTFIELDS, $fields);
$output = curl_exec($cho);
$info = curl_getinfo($cho);

// print_r($info);

$oauth = json_decode($output, true);
$token = $oauth['access_token'];

// print_r($token);

// inizio a chiamare le API 

$all_channels = [];
foreach($channels as $chans){
    if (count($chans) > 0) {
    $callAPI = implode('&user_login=', $chans);
    $url="https://api.twitch.tv/helix/streams?user_login=" . $callAPI;
    $ch = curl_init();
  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(

        'Client-ID: c533u8ntdp29h42xxzwfe0pf5v66dm',
        'Authorization: Bearer '.$token
  
    ));
    
    $result = curl_exec($ch);
    $i = curl_getinfo($ch);
    curl_close($ch);

    // preparo le stamp per le API
    $str = json_decode($result, true);
    if ($i['http_code'] == 200) {
        // play print API
        foreach ($str['data'] as $live_chan){
            $all_channels[] = $live_chan;
        }
        // do stuff with $str has chnanels
    } else {
        // non 200 do somethign with the error
        // do stuff with $str has error message
    }

    // print_r($url);
    // fine chiamata API
}
}

This for count total views (but not works):

foreach($all_channels as $mydata){
$views     = $mydata['viewer_count'];
$viewss = (array)$views;
$viewsss = implode('+', (array)$views);
$totv = array_sum($viewsss);
}
echo $totv;
