Smart and Readable Documentation for your PHP project

Just look at CakePHP Framework or Doctrine ORM API.

Note! This is 4.2 branch, final 4.x series of ApiGen. The project is undergoing a rewrite (5.x series on master). Please submit any PRs for versions 4.2.x to 4.2 branch.

Requirements

• PHP 5.5+

Install

Install using composer as a development dependency in your project:

composer require --dev apigen/apigen

Or if you want it globally:

composer global require --dev apigen/apigen

Usage

Run ApiGen with source and destination options:

vendor/bin/apigen generate -s ./src -d ./docs

To omit cli options just create apigen.yaml or apigen.neon file in your project's root folder:

source:
    - ./src

destination: ./docs

For all available options, along with descriptions and default values, just run:

vendor/bin/apigen generate --help

DocBlock Annotations

This section provides a list of PHP DocBlock annotations (tags) that are supported by ApiGen:

• @author - documents the author of the associated element.
• @copyright - documents the copyright information for the associated element.
• @deprected - indicated that the associated element is deprecated and can be removed in the future version.
• @internal - denotes that the associated elements is internal to this application or library and hides it by default.
• @license - indicates which license is applicable for the associated element.
• @link - indicates a relation between the associated element and a page of a website.
• @method - allows a class to know which ‘magic’ methods are callable.
• @package - categorizes the associated element into a logical grouping or subdivision.
• @param - documents a single argument of a function or method.
• @property - allows a class to know which ‘magic’ properties are present.
• @return - documents the return value of functions or methods.
• @see - indicates a reference from the associated element to a website or other elements.
• @subpackage - categorizes the associated element into a logical grouping or subdivision.
• @throws - indicates whether the associated element could throw a specific type of exception.
• @usedby indicates a "from" reference with a single associated element.
• @uses - indicates a reference to (and from) a single associated element.

Configuration

This section provides information on all available configuration options that can be included in configuration files (apigen.yml or apigen.neon).

Minimal Configuration

A minimal configuration file:

# apigen.neon.dist
# This is minimal configuration for ApiGen.
source: [src]           # directory(-ies) to scan PHP files from
destination: docs       # destination directory to generate API docs in

Note! The configuration files match CLI options for generate command. The only difference is that when defining these options in configuration file, you have to use camelCased format (i.e. --annotation-groups CLI option becomes annotationGroups configuration parameter).

Reference Configuration

A reference configuration file with all of the available and supported configuration options.

# apigen.neon.dist
# This is reference configuration for ApiGen. It contains all of the available
# and supported configuration options, together with their default values.
# source options
