Errr yeah no idea what you are trying to do with that bit of PHP there…
if ($i['http_code'] == 200) {
// play print API
$total = 0;
foreach ($str['data'] as $live_chan){
$total += $live_chan['viewer_count'];
}
echo $total;
} else {
// non 200 do somethign with the error
// do stuff with $str has error message
}
