# Access Control Knowledge Base
Quick reference for access control models, authorization patterns, and PHP implementations.
## Access Control Models Comparison
| Model | Full Name | Basis | Granularity | Scalability | Complexity |
|-------|-----------|-------|-------------|-------------|------------|
| **ACL** | Access Control List | Per-resource permissions | Fine | Poor at scale | Low |
| **RBAC** | Role-Based Access Control | Roles assigned to users | Medium | Good | Medium |
| **ABAC** | Attribute-Based Access Control | Policies over attributes | Very fine | Excellent | High |
| **ReBAC** | Relationship-Based Access Control | Object relationships | Very fine | Excellent | High |
