## Using Options
54+
55+
You can define some configurations using Symfony's Runtime `APP_RUNTIME_OPTIONS` API.
56+
57+
| Option | Description | Default |
58+
| --- | --- | --- |
59+
| `host` | The host where the server should binds to (precedes `SWOOLE_HOST` environment variable) | `127.0.0.1` |
60+
| `port` | The port where the server should be listing (precedes `SWOOLE_PORT` environment variable) | `8000` |
61+
| `mode` | Swoole's server mode (precedes `SWOOLE_MODE` environment variable) | `SWOOLE_PROCESS` |
62+
| `settings` | All Swoole's server settings ([swoole.co.uk/docs/modules/swoole-server/configuration](https://www.swoole.co.uk/docs/modules/swoole-server/configuration)) | `[]` |
63+
64+
```php
65+
// public/index.php
66+
67+
use App\Kernel;
68+
69+
$_SERVER['APP_RUNTIME_OPTIONS'] = [
70+

'port' => 9501,
72+
'mode' => SWOOLE_BASE,
73+

75+
