Akelos is an MVC framework for PHP that tries to bring the magic of Ruby on Rails to the PHP world. Akelos based applications can run on most shared hosting service providers since Akelos only requires a standard PHP installation on the server. Akelos is designed to make developers lives simpler by solving complex problems with unusual speed and productivity. Favoring "convention over configuration" leads to the creation of uniform and simpler-to-understand code.
PhpBase is a set of PHP classes and functions aimed to help developers submit their data to Google Base. The main purpose for a tool like this is the need to keep data submissions accurate and avoid common errors that might occur when submitting to standard schemes recommended by Google. It has a plug-in style for attributes and schemes. Currently, only a Housing scheme is defined.
The XhtmlValidator is a PHP class that can be used to validate XHTML documents. It uses only the expat extension functions, which are always available in PHP, so it does not need other external XML processing extensions. The class parses the documents and checks whether the tags and attributes used by the documents are allowed within the XHTML standard. If validation errors are found, highlighted error messages and offending document line numbers will be returned.
