GNU phpGrabComics is a web application (based on PHP and MySQL) for downloading comic strips from the web. The main aim of phpGrabComics is to help users to read and archive their favourite comic strips.
It supports grabbing today's strip from several sites, such as Dilbert, Calvin and Hobbes, Peanuts and Il manifesto.
The phpGrabComics server allows to download comic strips from different sources and to automatically save the comics.
A phpGrabComics server can be used by phpGrabComics ports, tiny applications aimed to the final user. phpGrabComics ports get from the server the list of available comics and the information on how to retrieve the comics. The ports can always use the latest list of comics, as soon as they are available in a phpGrabComics server.
RSS readers can be used to read the links to comics strips provided by a phpGrabComics server.
Developed by Andres Baravalle, phpGrabComics is Free Software released under the GNU General Public License.
It requires a web server which supports the PHP extension (such as the Apache HTTP Server), the GD module, and a MySQL database.
