Dephpend

Dephpend is a static analysis tool for PHP that focuses on analyzing and visualizing dependencies within a codebase. It provides insights into the architecture and structure of PHP projects by identifying the relationships between different components, such as classes and namespaces. Dephpend helps developers understand the coupling and dependencies in their code, which is crucial for maintaining a modular and scalable architecture.

Key Features of Dephpend:

1. Dependency Graphs: It generates visual representations of how different parts of the application are interconnected.
2. Architectural Analysis: Dephpend helps ensure that the architecture follows design principles, such as the Dependency Inversion Principle (DIP).
3. Modularity: It helps identify areas where the code may be too tightly coupled, leading to poor modularity and making the code harder to maintain or extend.
4. Layer Violations: Dephpend can spot violations where code in higher layers depends on lower layers inappropriately, aiding in cleaner architectural patterns like hexagonal architecture.

This tool is particularly useful in large codebases where maintaining a clear architecture is essential for scaling and reducing technical debt. By visualizing dependencies, developers can refactor code more confidently and ensure that new additions don't introduce unwanted complexity.
