Application Framework

All-in-one PHP framework and UI layer for building web and intranet applications.

Introduction

The framework is designed to be a solid foundation for custom-built web applications. The integrated functionality helps to focus on the application logic, while being able to create the necessary administration screens, APIs and more with minimal effort.

Note that it is not a CMS: it is exclusively a tool for building custom applications. Supporting features are available out of the box, like the notepad or image library, but anything your application needs to do must be implemented by you.

One of the core functionalities of the framework is to provide an extensive ecology of classes for accessing custom data stored in the database. This includes complex filtering capabilities as well as a versioning system with record state tracking (draft, published, etc.).

Features overview

• PHP helper classes for UI elements
• Form building system - every screen is a form
• Rule-based application environment detection
• Advanced database-stored data handling tools
• Class-based extensible templating system
• Localization system for UI translation
• News central (release notes, etc.)
• Event handling system
• Image media library and UI
• Tagging system and UI
• Versioning system with state tracking
• Disposables system for automated garbage collection
• API response caching (file-based, opt-in via Interface + Trait; TTL and manual strategies)
• SSO via CAS
• Interface Translations: English, German, French
• Build-time module documentation generators (Modules Overview, Keyword Glossary)
• Own ecology of supporting libraries

Requirements

• PHP 7.4 or higher (fully PHP 8 compatible)
• Composer
• MariaDB or MySQL database with InnoDB support
• Webserver

Installation

The framework can be installed as a regular Composer dependency. However, the required application skeleton of folders and files can currently only be generated dynamically using the Framework Manager, which is currently still a private project.

Documentation on how to set up an application using the framework is still in progress. In the meantime, the example application can be used as a reference (see Example application).

Example application

The framework includes a sample application which is used as a reference for available features, best practices, and testing. It can also be used as the basis for a new application.

You will find it in the tests/application folder.

Installation

The quickest way to set up the example application is with the interactive setup command:

This will prompt you for database and UI settings, create the database if it does not exist, import docs/sql/pristine.sql, and seed the test data automatically. Re-running the command is safe — existing values are shown as defaults and pressing Enter preserves them.

After setup, access the tests/application folder via the webserver.

Note: The generated config files (test-db-config.php, test-ui-config.php) are listed in .gitignore and must never be committed to version control — they contain local credentials and are derived from the .dist.php templates.

Composer commands

These are custom Composer commands that are available when developing locally.

Build

The build step generates module documentation artefacts from module-context.yaml files discovered throughout the codebase, updates the CTX generated-at.txt timestamp, regenerates the API method index, and rebuilds offline event listeners.

For the full development build (includes module glossary and keyword index):

Setup

Interactive one-command setup for the local development environment. Prompts for database and UI settings, generates test-db-config.php and test-ui-config.php from their .dist.php templates, creates the database if it does not exist, imports docs/sql/pristine.sql, and runs composer seed-tests automatically on completion.

Re-running the command is safe (idempotent): existing config values are read back and shown as defaults; pressing Enter without typing preserves them. If the database connection fails, the script re-prompts for credentials until a successful connection is established.

The script can also be invoked directly:

Requires an interactive terminal (TTY). Do not pipe or redirect input to this command — stty -echo (used to suppress password echo) relies on an attached TTY and will behave unexpectedly in non-interactive contexts.

Seed test database

Truncates all tables in the test database and re-populates them with the standard framework seed data (system users, locales, and countries). Run this once after importing docs/sql/pristine.sql, and again whenever the test database needs to be reset to a known state.

The command runs two process-isolated steps in sequence:

1. php tools/seed-truncate.php — empties all base tables
2. php tools/seed-insert.php — inserts system users, locales, and countries

The command requires the test database to be accessible and configured (see tests/application/config/test-db-config.php). It is idempotent: running it on an already-seeded database produces the same result with no errors. On failure it prints a human-readable error message and exits with code 1, making it safe to use in CI pipelines.

Clear caches

Clears all caches used by the framework, including the dynamic class cache.

Developer Tools

The tools/ directory contains local-development CLI scripts. These are version-controlled and intended for developer use only — they are not part of the framework runtime.

Getting started as a contributor

The fastest way to get your local environment up and running is the interactive developer menu. From the project root, run:

The menu will automatically run composer install if vendor/ is missing, then present a numbered list of common tasks. Choose option 1 to run the interactive local-environment setup wizard, which configures the database and generates the required config files.

Setup Script

tools/setup-local.php is the interactive local-environment setup script (see composer setup above). It can be run directly with php tools/setup-local.php or via composer setup.

Generated files and version control

The script generates tests/application/config/test-db-config.php and tests/application/config/test-ui-config.php from their .dist.php counterparts. Both generated files are listed in .gitignore and must not be committed — they contain local database credentials. The .dist.php templates (which contain no credentials) are version-controlled and serve as the canonical structure reference.

Platform and TTY notes

CAS authentication mode

By default the setup script writes TESTS_SESSION_TYPE = 'NoAuth' into test-ui-config.php. This setting is not prompted interactively — it must be changed manually when CAS authentication is required.

To enable CAS mode:

1. Open tests/application/config/test-ui-config.php and change the constant:

2. Copy the CAS configuration template and fill in your server details:

3. Edit test-cas-config.php and set the following constants to match your CAS / LDAP environment:

   Constant	Description
   APP_CAS_HOST	CAS server hostname (e.g. cas.example.com)
   APP_CAS_PORT	CAS server port (default 443)
   TESTS_CAS_FIELD_EMAIL	CAS response field for the user's email address
   TESTS_CAS_FIELD_FIRST_NAME	CAS response field for given name
   TESTS_CAS_FIELD_LAST_NAME	CAS response field for family name
   TESTS_CAS_FIELD_FOREIGN_ID	CAS response field used as the external user ID
   APP_LDAP_HOST / APP_LDAP_PORT	LDAP server connection details
   APP_LDAP_DN / APP_LDAP_USERNAME / APP_LDAP_PASSWORD	LDAP bind credentials

test-cas-config.php is gitignored alongside the other generated config files — it must never be committed.

CLI Utility Library

tools/include/cli-utilities.php is the shared helper library included by every script in tools/. It provides four console I/O functions:

All functions are guarded with function_exists() so the file can be safely included more than once.

Developer Menu

An interactive numbered menu that groups the most common developer tasks in a single entry point. Launch it from the project root with:

If the vendor/ directory is missing when the menu starts, composer install is run automatically before the menu is displayed.

Available options

Option 3 (Run tests) sub-prompts for an optional filter pattern. Leaving it empty runs the full test suite; entering a pattern runs only matching tests.

The menu loops after each action completes so you can run multiple tasks in sequence without re-launching the script.

Launchers

Build-Time Documentation Generators

The Application\Composer namespace provides build-time utilities that generate two Markdown documentation artefacts automatically on every composer build:

• Modules Overview (docs/agents/project-manifest/modules-overview.md) — a Markdown table of all modules, their source paths, context doc locations, and inter-module dependencies. Discovered from module-context.yaml files.
• Keyword Glossary (docs/agents/project-manifest/module-glossary.md) — a Markdown glossary mapping opaque domain terms to the modules that define them. Application modules can contribute custom sections via the DecorateGlossaryEvent offline event.

To register a module for discovery, add a module-context.yaml next to its classes:

See src/classes/Application/Composer/README.md for full API documentation and the offline-event integration guide.

CTX Integration

The project uses CTX to generate context files for AI-assisted development, and to provide an MCP server for integration with IDEs like PHPStorm to access the framework's AI tools.

This fetches a JSON-lines list of configurations and tools available in the server.

Documentation

The framework's documentation is available locally by pointing a browser to the docs folder, and online in the separate Framework Documentation package.

It is ideally viewed through the framework's documentation screen, as there are some features that are only available there (like code samples that are included dynamically).

Vendor Package

For convenience, a copy of the documentation is automatically checked out into the vendor folder during the Composer install process.

It can be found at mistralys/application-framework-docs.

History

The framework has its origins in several projects where the same development paradigms were used and refined over time. In 2013, it started to crystallize into a recognizable entity, and in 2015, it was officially split off into its own project.

It was migrated to Github in february 2021, and modernizing the code has been ongoing ever since. As a result, the current state of the code is a mix of namespaced and non-namespaced code, with the goal of eventually moving to a fully namespaced codebase.
