Drupal is a modular content management system, forum, blogging and community engine. It is database driven and can be used with MySQL, MariaDB, PostgreSQL, and SQLite. Its features include (but are not limited to) discussion forums, Web-based administration, theme support, a submission queue, content rating, content versioning, taxonomy support, user management with a fine-grained permission system based on user roles (groups), error logging, support for content syndication, locale support, and much more. It is considered to be an excellent platform for developers due to its clean code and extensibility, and it can also be used as a Web application framework.
Ariadne is a Web Application Framework and Content Management System built with PHP. It allows you to build complex Web applications and sites with ease. It takes care of the mundane stuff like internationalization, security, user management, templating, data retrieval and storage, caching, and site management. It stores content in a structured object store that can be accessed through an extensive filesystem-like API.
The adventure PHP framework (APF) is a utility to implement object oriented and generic PHP Web applications. It allows the developer to create programs in compliance with approved software design patterns, and the code base already has answers to many everyday problems. The framework cannot be described as an application that only has to be configured, but rather as a technical basis and design guide for the design of software. Further, it introduced many concepts and efficiency tools already well known in the Java community.
Valentina is cross-platform SQL and non-SQL columnar database that allows development of client-server [Web] solutions and applications with an embedded local database using the same sources. Valentina DB provides an Object-Relational model, but you can also mix Relational and Extended Navigational. It introduces a revolutionary model abstraction "Link" that greatly simplifies db schema, and therefore simplifies SQL queries. It supports disk and in-memory databases, and field types including Bit, BLOB, Pictures, and Enum. It provides advanced features such as triggers, views, stored procedures, regular expressions, XML, full-text search, and calculated fields. It exists as Valentina Server, Valentina Studio, and a set of Valentina ADKs for all major programming languages.
Adaptive Website Framework (AWF) is a modern content management system and development framework. Most of its code is object-oriented and very easy to extend. It features support for multiple Web sites and languages, content versioning, caching, community portal functions (online list, forums, instant messages, newsletters, weblogs, wiki, etc.), image upload and galleries, a lexicon, a modular full-text search engine, an auto repair function for database tables, XML and PDF export, and RSS and LDAP support. Changes can be made on a preview site and published at a later time on the live site. Fully flexible URLs allow the replacement of existing static Web sites.
Xataface is a flexible and shapable skin that sits on top of MySQL, making it accessible to every-day users. It automatically generates the appropriate forms, lists, and menus for a user to interact with the database without having to know any SQL. It is a full-featured Web application framework, and gives developers the flexibility to customize the features and behavior of their application via configuration files (using the simple INI-file syntax), templates, and plug-ins. A generic application with no customizations is completely functional, but the developer is free to customize things at his leisure.
Midgard is a persistent storage framework. It provides an object-oriented and replicated environment for building data-intensive applications. It ships with a MidCOM content management system built on the Midgard framework. MidCOM's features include Web-based authoring WYSIWYG interfaces and a component interface for installing additional Web functionality. Midgard is built on the GNOME stack of libraries like GLib and libgda, and has language bindings for C, Python, and PHP. Communications between applications written in the different languages happen over D-Bus. The CMS runs on the LAMP (Linux, Apache, MySQL and PHP) platform.
WACS is a tool for building adult Web sites. It is equally suitable for managing a private collection or building a commercial site. WACS has many best of breed features, including dynamic filtering, model catalogs, random sampling, galleries, automatic download, and a powerful search engine. WACS contains both a full ready-to-run Web environment and an extensive programming API implemented in both Perl and PHP.
P4A (PHP For Applications) a PHP5 RAD and object oriented PHP framework for building event-driven, stateful Web applications. It is based on Zend Framework and features tableless HTML, multiple databases, access key support, auto data type recognition, transparent AJAX, UTF-8, internationalization, and localization.
PhpPeanuts is a framework for developing database-backed applications in PHP. Rather than building an application from the bottom up, you initially only build domain model classes in which you specify properties, relationships, and database table names in metadata. The framework dynamically scaffolds getters and setters, persistency, navigation over relations, and input and delete validation. The abstract user interface instantly offers a rich set of pages for searching, browsing, drilling down, editing and reporting over your domain model. From there on you extend and refine both the domain model and the user interface to make it what you want by defining specialization classes and overriding inherited methods.
