PhpDependencyAnalysis is an extendable static code analysis for object-oriented PHP-Projects to generate dependency graphs from abstract datatypes (Classes, Interfaces and Traits) based on namespaces. 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 for further informations.


See more examples.


As a Docker Image (recommend way)

docker pull mamuz/phpda

As a Composer Dependency

NOTE: For graph creation GraphViz is required on your machine, which is an open source graph visualization software and available for the most platforms.

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

As a Phar

Since version 2.0.0 not supported anymore.


  • 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 and Anonymous Classes


Phpda can run out of the box by using a prepared configuration. As you can see configuration is defined by a YAML file.

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

mode: 'usage'
source: './src'
filePattern: '*.php'
ignore: 'tests'
formatter: 'PhpDA\Writer\Strategy\Svg'
target: './phpda.svg'
groupLength: 1
  - PhpDA\Parser\Visitor\TagCollector
  - PhpDA\Parser\Visitor\SuperglobalCollector
  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:

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