# Installation

## In a Symfony application

```bash
composer require spomky-labs/access-control-bundle
```

Register the bundle. **There is no `enabled` flag: registering it is the opt-in.**

```php
// config/bundles.php
return [
    // ...
    AccessControl\Bundle\AccessControlBundle::class => ['all' => true],
];
```

That is the whole of day one. If your application has SecurityBundle, nothing you can see changes: your voters keep being consulted, `#[IsGranted]` is read, `is_granted()` answers in your templates, and the rules of your `security.yaml` are enforced. What changed is who decides. See [The Two Migrations](/migration/the-two-migrations.md).

## In any PHP application

```bash
composer require spomky-labs/access-control-lib
```

No container and no framework are needed:

```php
use AccessControl\AccessControlManager;
use AccessControl\AccessRequest;
use AccessControl\Strategy\PermitOverridesStrategy;

$accessControlManager = new AccessControlManager(
    strategies: [new PermitOverridesStrategy()],
    voters: [new PostVoter()],
);

$decision = $accessControlManager->decide(new AccessRequest($requester, 'EDIT', $post));
```

See [The Manager](/pure-php/the-manager.md).

## Requirements

* PHP 8.4 or later.
* Symfony 8.1 or later, for the bundle.

## Optional packages

The library requires almost nothing. These unlock features, and their absence is never an error:

| Package                       | What it unlocks                                                                             |
| ----------------------------- | ------------------------------------------------------------------------------------------- |
| `symfony/security-core`       | Reusing voters, tokens and the role hierarchy of Symfony Security                           |
| `symfony/expression-language` | Attributes and conditions given as an `Expression`, and the `allow_if` option of a URL rule |
| `twig/twig`                   | The template functions                                                                      |
| `symfony/workflow`            | Guarding workflow transitions                                                               |
| `symfony/console`             | Guarding console commands                                                                   |
| `symfony/web-profiler-bundle` | The profiler panel                                                                          |

**One exception worth knowing about.** Guarding a workflow transition requires `symfony/security-core` to be *installed*, even though this component never uses it there: Symfony's `FrameworkExtension` refuses a guard expression at compile time without it, before this bundle gets a chance to replace the listener. Install it and nothing more. See [Workflow Guards](/the-symfony-bundle/workflow.md).

## Checking it is on

```bash
bin/console debug:container --tag=access_control.voter
```

Or open a page with the profiler enabled: the panel says which stack answered, and lists every question the request asked. See [The Profiler Panel](/the-symfony-bundle/profiler.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://acf.spomky-labs.com/the-project/installation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
