[Back to constructors index](index.md)



### Attributes:

| Name     |    Type       | Required |
|----------|:-------------:|---------:|
|date|[int](../types/int.md) | Yes|
|expires|[int](../types/int.md) | Yes|
|test\_mode|[Bool](../types/Bool.md) | Yes|
|this\_dc|[int](../types/int.md) | Yes|
|dc\_options|Array of [DcOption](../types/DcOption.md) | Yes|
|chat\_big\_size|[int](../types/int.md) | Yes|
|chat\_size\_max|[int](../types/int.md) | Yes|
|broadcast\_size\_max|[int](../types/int.md) | Yes|
|disabled\_features|Array of [DisabledFeature](../types/DisabledFeature.md) | Yes|



### Type: [Config](../types/Config.md)


### Example:

```
$config = ['_' => 'config', 'date' => int, 'expires' => int, 'test_mode' => Bool, 'this_dc' => int, 'dc_options' => [DcOption], 'chat_big_size' => int, 'chat_size_max' => int, 'broadcast_size_max' => int, 'disabled_features' => [DisabledFeature], ];
```  

[PWRTelegram](https://pwrtelegram.xyz) json-encoded version:

```
{"_":"config","date":"int","expires":"int","test_mode":"Bool","this_dc":"int","dc_options":["DcOption"],"chat_big_size":"int","chat_size_max":"int","broadcast_size_max":"int","disabled_features":["DisabledFeature"]}
```


Or, if you're into Lua:  


```
config={_='config', date=int, expires=int, test_mode=Bool, this_dc=int, dc_options={DcOption}, chat_big_size=int, chat_size_max=int, broadcast_size_max=int, disabled_features={DisabledFeature}, }

```
