Chamilo LMS is a PHP-based Learning Management System built with Symfony framework and Vue.js frontend. It provides course management, assessments, gradebook, attendance tracking, and collaboration tools through a modular plugin architecture. The system features RESTful API endpoints consumed by Vue services, Doctrine ORM for data persistence, and supports over 60 languages. While actively modernizing with Vue.js 3 and Symfony 6, it maintains legacy PHP components alongside new implementations, creating some technical debt from gradual migration. The plugin system follows a standardized structure enabling extensibility, and the codebase demonstrates solid engineering practices with clear separation of concerns between CoreBundle, CourseBundle, and PluginBundle.
ILIAS is a large, modular, open-source Learning Management System (LMS) written primarily in PHP. In production, it provides a full-featured e-learning platform including course management, tests and assessments, surveys, forums, wikis, blogs, portfolios, SCORM content, certificates, chat, and social features. The architecture is a monolithic PHP web application with a component-based internal structure under `components/ILIAS/`. It uses dependency injection (DIC), ilCtrl for routing, a custom UI framework (ILIAS\UI) with factory and renderer patterns, GlobalScreen for top-level UI orchestration, and COPage for rich content editing. Entry points include `cli/setup.php` (installation), `cli/cron.php` (cron jobs), `login.php`, and various web service endpoints (SOAP, WebDAV, REST). External dependencies include MySQL, Node.js (for the chat server), and optional integrations like LDAP, Shibboleth, and LTI. The codebase shows active modernization with PHP 8.3/8.4, strict types, enums, and a structured setup/migration system, though it still carries legacy patterns (e.g., global `$DIC`, old GUI classes) that are being phased out via PHPStan rules and deprecation notices.
