i have been learning about kafka and laravel.

so i'm trying to implement kafka(using rdkafka) in laravel, but i have a problem

when i tried to use kafka in php, everything works fine in pure php, but i got an error when i tried to implement it in laravel as a command class

```
$conf = new RdKafka\Conf(); 

```

i think that's the problem, 
RdKafka is a dynamic extension in php.ini(i added it manually directly from php.ini) and become undefined when i tried to implement in laravel and i don't know how to solve it. 

how to use dynamic extension in laravel?

here is the command class and consumer function tutorial from rdkafka 

```
namespace App\Console\Commands;
use Illuminate\Console\Command;

class ExampleCommand extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'command:name';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Command description';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {

        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        //
        $conf = new RdKafka\Conf();

        $conf->set('group.id', 'myConsumerGroup');

        $rk = new RdKafka\Consumer($conf);
        $rk->addBrokers("127.0.0.1");

        $topicConf = new RdKafka\TopicConf();

        $topicConf->set('auto.commit.interval.ms', 100);
        $topicConf->set('offset.store.method', 'file');
        $topicConf->set('offset.store.path', sys_get_temp_dir());

        $topicConf->set('auto.offset.reset', 'smallest');

        $topic = $rk->newTopic("test", $topicConf);

        $topic->consumeStart(0, RD_KAFKA_OFFSET_STORED);

        while (true) {
            $message = $topic->consume(0, 120*10000);
            switch ($message->err) {
                case RD_KAFKA_RESP_ERR_NO_ERROR:
                    var_dump($message);
                    break;
                case RD_KAFKA_RESP_ERR__PARTITION_EOF:
                    echo "No more messages; will wait for more\n";
                    break;
                case RD_KAFKA_RESP_ERR__TIMED_OUT:
                    echo "Timed out\n";
                    break;
                default:
                    throw new \Exception($message->errstr(), $message->err);
                    break;
            }
        }

    }
}

```
