`Policy Evaluator` is a simple system based on AWS Policies. Given a set of statements, `Policy Evaluator` will then be able to answers to queries about whether this set of policies is allowed (or not) to perform a given action on a given resource.

Getting started
---------------

[](#getting-started)

`php composer.phar require tomzx/policy-evaluator`

Example
-------

[](#example)

```
use tomzx\PolicyEvaluator\Evaluator;
use tomzx\PolicyEvaluator\Resource;

Resource::$prefix = 'arn';

$evaluator = new Evaluator([
	'Statement' => [
		[
			'Action' => 'service:*',
			'Resource' => 'arn:aws:*',
			'Effect' => 'Allow',
		],
		[
			'Action' => 's3:*',
			'Resource' => 'arn:aws:s3:::my-bucket/*',
			'Effect' => 'Allow',
		],
	],
]);

$evaluator->canExecuteActionOnResource('service:test', 'arn:aws:test');
$evaluator->canExecuteActionOnResource('s3:GetObject', 'arn:aws:s3:::my-bucket/some-file');
```

### Variables support
