CairoForPHP is an application that demonstrates several functions of the Cairo implementation for PHP. It uses a technique with which, from the same source, it can run both as a desktop application with PHP-GTK and as a Web application, thus demonstrating how PHP-GTK can be used as "just one" method of output and integrated into multi-platform, multi-environment applications. The samples in CairoForPHP are fully adjustable, and code can be "dropped-in" easily in the non-Phar versions: all required additional data interfaces are XML-based. The integrated samples come both pre-rendered and in live rendering, demonstrating both abilities of Cairo here and PHP-GTK's utilization with Cairo in the realization of it. CairoForPHP uses several technologies in order to achieve all this, such as XML-based data interfaces (including XML Schema validation), PHP-GTK, Phar compatibility, Gettext integration, and others.
