Question

My code:

private function getServerInfo($servers){
    $result = array();

    foreach ($servers as $key => $value) {

        $ch = curl_init();

        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        curl_setopt($ch, CURLOPT_URL,"https://mcapi.de/api/server-query/".$servers[$key]->ip.":".$servers[$key]->port."");

        $result[$key] = json_decode(curl_exec($ch), true);

        curl_close($ch);
    }

    return $result;
}

What am I doing wrong? I'm trying to check 16 server IPs and each one takes 1 second.
