How to execute

Class Diagram

When three php source files that TYPE commented exist in test/fixtures/no-namespace,

  • php source files.
  • Product.php
class Product {
    /** @var Name   product name. */
    private $name;
    /** @var Price  price of product. */
    private $price;
  • Name.php
class Name {
    /** @var string  name. */
    private $name;
  • Price.php
class Price {
    /** @var int  price. */
    private int $price;

To execute php-class-diagram will print PlantUML script.

$ vendor/bin/php-class-diagram test/fixtures/no-namespace
@startuml class-diagram
  package product as product <<Rectangle>> {
    class product.Price {
      -price : int
    class product.Name {
      -name : string
    class product.Product {
      -name : Name
      -price : Price
  product.Product ..> product.Name
  product.Product ..> product.Price

Use PlnatUML to convert the PlantUML script to an image.

PlantUML output image.

Package Diagram

You can visualize package dependencies by creating a package relationship diagram with php-class-diagram.

$ vendor/bin/php-class-diagram --package-diagram test/fixtures/dependency-loops
@startuml package-related-diagram
  package hoge.fuga as ROOT {
    package product as product {
      package attribute as product.attribute {
      package config as product.config {
  product --> product.attribute
  product <-[#red,plain,thickness=4]-> product.config

Packages that depend on each other are not desirable. If it finds packages that depend on each other, it will warn you with a thick red line.
