- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.

Attribute-Based Access Control implementation library
Introduction
This library is meant to implement the concept of ABAC in your PHP applications.
The concept is to manage access control using attributes : from users, from resources and environment.
It allows us to define rules based on the properties of the user object and optionally the accessed object.
These rules will be checked in your application to determine if an user is allowed to perform an action.
The following links explain what ABAC is :
Installation
Using composer :
Then you will have to configure the attributes and the rules of your application.
For more details about this, please refer to the dedicated documentation
Documentation
- Configuration
- Dependency Injection
- Access-control
- Comparisons
- Caching
Usage Examples
Example with only user attributes defined in the rule
We have in this example a single object, representing the current user.
This object have properties, with getter methods to access the values.
For example, we can code :
The attributes checked by the rule can be :
| User |
|---|
| isBanned = false |
Example with both user and object attributes
The checked attributes can be :
| User | Group |
|---|---|
| isBanned = 0 | isActive = 1 |
| isPublic = 1 |
Example with dynamic attributes
Example with referenced attributes
The configuration shall be :
And then the code :
Example with cache
Example with multiple rules (ruleSet) for an unique rule. Each rule are tested and the treatment stop when the first rule of the ruleSet allow access
The configuration shall be (alcoolaw.yml):
And then the code :
Example with rules root directory passed to Abac class. This feature allow to give a policy definition rules directory path directly to the Abac class without adding to all files :
Considering we have 3 yaml files :
- rest/conf/policy/user_def.yml
- rest/conf/policy/gunlaw.yml
The php code can be :
