Joomla PHP Pages Component - allows you to create simple PHP pages and link them to the Joomla Menu. This allows you to easily create a custom page without having to create a whole component. It is similar to the PHP Module for Joomla, except that it is a full Component.

Custom PHP Content Plugin - is a mambot mambot/plugin that allows you to place custom PHP inside a Joomla mambot, thus allowing you to modify the Joomla Articles before it is displayed. A very powerful tool if you are familiar with how Joomla implements mambots/plugins, but can also be used for simple addition of PHP code into your content.

AMFPHP - is a way to provide Flash/Flex remoting services on an Apache/PHP platform instead of requiring your server to be a Cold Fusion server. J-AMFPHP add AMFPHP as a plugin for Joomla, exposing the Joomla API to AMFPHP services. This has the benefit of using all the Joommla core API for managing the database, connecting with other components and modules, etc, without rewriting everything a second time. This component is for developers only! It is intended to make it easier for developers to build front-end Flash modules and components driven by Joomla content. This is not meant for end-users or general site administrators who are not familiar with developing their own modules and plugins. Make sure to install the additional Discovery Service plugin if you intend to use the AMFPHP browser. Also, try out the Example Services plugin to see how easy it is to build your own services as Joomla plugins.
