PhpDependencyAnalysis is an extendable static code analysis for object-oriented

PHP-Projects to generate [`dependency graphs`](http://en.wikipedia.org/wiki/Dependency_graph)

from abstract datatypes (Classes, Interfaces and Traits) based on [`namespaces`](http://php.net/manual/en/language.namespaces.php).

Dependencies can be aggregated to build graphs for several levels, like Package-Level or Layer-Level.

Each dependency can be verified to a defined architecture.



Read the [Introduction-Chapter](https://github.com/mamuz/PhpDependencyAnalysis/wiki/1.-Introduction) for further informations.



### Example



![](https://cdn.rawgit.com/mamuz/PhpDependencyAnalysis/master/tests/_data/svg/expectation/packages.svg)



See more [examples](https://github.com/mamuz/PhpDependencyAnalysis/wiki/4.-Examples).



## Installation



### As a Docker Image (recommend way)



```bash

docker pull mamuz/phpda

```



### As a Composer Dependency



**NOTE:** For graph creation [`GraphViz`](http://www.graphviz.org/) is required on your machine, which is

an open source graph visualization software and available for the most platforms.



```sh

$ composer require --dev mamuz/php-dependency-analysis

```



### As a Phar



Since version 2.0.0 not supported anymore.



## Features



- High customizing level

- Graph creation on customized levels respectively different scopes and layers

- Supports Usage-Graph, Call-Graph and Inheritance-Graph

- Dependencies can be aggregated such as to a package, a module or a layer

- Detecting cycles and violations between layers in a tiered architecture

- Verifiying dependency graph against a user-defined reference architecture

- Collected namespaces of dependencies are modifiable to meet custom use cases

- Printing graphs in several formats (HTML, SVG, DOT, JSON)

- Extandable by adding user-defined plugins for collecting and displaying

- Compatible to PHP7 Features, like [`Return Type Declarations`](https://wiki.php.net/rfc/return_types) and [`Anonymous Classes`](https://wiki.php.net/rfc/anonymous_classes)



## Usage



Phpda can run out of the box by using a prepared [`configuration`](https://github.com/mamuz/PhpDependencyAnalysis/blob/master/phpda.yml.dist).

As you can see configuration is defined by a [`YAML`](http://en.wikipedia.org/wiki/YAML) file.



To provide your own configuration create a yml file, e.g. located in `./phpda.yml`:



```yml

mode: 'usage'

source: './src'

filePattern: '*.php'

ignore: 'tests'

formatter: 'PhpDA\Writer\Strategy\Svg'

target: './phpda.svg'

groupLength: 1

visitor:

  - PhpDA\Parser\Visitor\TagCollector

  - PhpDA\Parser\Visitor\SuperglobalCollector

visitorOptions:

  PhpDA\Parser\Visitor\Required\DeclaredNamespaceCollector: {minDepth: 2, sliceLength: 2}

  PhpDA\Parser\Visitor\Required\MetaNamespaceCollector: {minDepth: 2, sliceLength: 2}

  PhpDA\Parser\Visitor\Required\UsedNamespaceCollector: {minDepth: 2, sliceLength: 2}

  PhpDA\Parser\Visitor\TagCollector: {minDepth: 2, sliceLength: 2}

```



Perform an analysis with that configuration:



```sh

$ docker run --rm -v $PWD:/app mamuz/phpda

```



Read the [Configuration-Chapter](https://github.com/mamuz/PhpDependencyAnalysis/wiki/3.-Configuration)

to get knowledge about all available options.
