Dependency Visualizer

Overview

Dependency Visualizer is a tool that visualizes dependency among classes.

This tool is experimental and possesses only basic functionality. For example, it doesn't have a mechanism to resolve expressions and infer types, nor does it interpret PHPDoc.

Installation

1. Edit composer.json

   {
       "repositories": [
           {
               "type": "vcs",
               "url": "https://github.com/hirokinoue/dependency-visualizer"
           }
       ],
       "minimum-stability": "dev",
       "prefer-stable": true
   }
   

   Please note that this tool is experimental. Consider whether your project can accept a minimum stability of 'dev' before installing it.

2. Install using composer
   $ composer require --dev hirokinoue/dependency-visualizer

Configuration

Add a config.php, config.php.dist or config.dist.php to the directory from which you run dependency-visualizer.

config.php looks like this:

<?php declare(strict_types=1);
return $config = [
    'memoryLimit' => '1024M',
    // Specify the number of depths to analyze in the dependency hierarchy.
    'maxDepth' => 5,
    // Specify a part of a namespace to exclude classes from the analysis.
    // For example, when dependencies of third-party packages are not wanted to be analyzed.
    // Classes starting with the given namespace will not be analyzed and classes they depend on will not.
    // Note that if A depends on B and C, and B depends on C, and B is excluded,
    // the dependence from A to C will be shown, but the dependence from B to C will not be shown.
    'endOfAnalysis' => [
        'Foo\\',
    ],
    // Specify a part of a namespace.
    // Classes starting with the given namespace will not be analyzed.
    'excludeFromAnalysis' => [
        'Foo\Bar\\',
    // Specify the relative path from the directory where the application is executed.
    'excludeFilePath' => [
        '',
    ],
];

Usage

$ ./vendor/bin/dependency-visualizer -h

Usage: dependency-visualizer [options] <target php file>
Options:
  -d: Load Xdebug.
  -h: Show this help.
  -l: Output log to current directory.
  -m: Draw methods in diagram.
  -s: Output analysis results in string format.

Example

Items that cannot be distinguished as concrete class, abstract class, interface, trait or enum are drawn as stereotype.
