#### Disabling Introspection
This is a PHP port of [graphql-disable-introspection](https://github.com/helfer/graphql-disable-introspection).
The rule prohibits queries that contain `__type` or `__schema` fields.
This document validator rule is disabled by default. Here an example to enable it:
```php
use GraphQL\GraphQL;
use GraphQL\Validator\Rules\DisableIntrospection;
/** @var \GraphQL\Validator\Rules\DisableIntrospection $disableIntrospection */
$disableIntrospection = DocumentValidator::getRule('DisableIntrospection');
$disableIntrospection->setEnabled(DisableIntrospection::ENABLED);
GraphQL::execute(/*...*/);
```
