Legal Things - Permission matcher
=================================

[](#legal-things---permission-matcher)

With the permission matcher library, you can check whether a user is allowed to have access to specific resources. Specifying resources and access control levels is up to the client of the library.

Requirements
------------

[](#requirements)

- [PHP](http://www.php.net) >= 5.6.0

*Required PHP extensions are marked by composer*

Installation
------------

[](#installation)

The library can be installed using composer.

```
composer require legalthings/permission-matcher

```

How it works
------------

[](#how-it-works)

The library exposes one function with which you can get a list of privileges for matching authz groups. Authz groups can be anything you want, in the example below resource URIs are used, but you could also use a string of any format. In the example we have a user that has certain permissions attached to him. We can then ask the `PermissionMatcher` class to extract the permissions of the users for a given authz group. Note that you can use wildcards `*`. You can also invert a permission by placing a `!` in front of the authz group.

```
$matcher = new PermissionMatcher();

$permissionsThatSomeUserHas = [
    '/organizations/0001' => ['full-access'],
    '/organizations/0002?list=all' => 'list',
    '/organizations/0003/*/foo' => ['read', 'write']
];

echo $matcher->match($permissionsThatSomeUserHas, ['/organizations/0001']);
// outputs ['full-access']

echo $matcher->match($permissionsThatSomeUserHas, ['/organizations/0001', '/organizations/0003/random/foo']);
// outputs ['full-access', 'read', 'write']

echo $matcher->match($permissionsThatSomeUserHas, ['/organizations/0002']);
// outputs []

echo $matcher->match($permissionsThatSomeUserHas, ['/organizations/0002?list=all']);
// outputs ['list']

echo $matcher->match($permissionsThatSomeUserHas, ['/organizations/*']);
// outputs ['full-access', 'read', 'write']
```
