bombusbee.com is a site devoted to the support and development of Fusebox for PHP. Fusebox is a free web application standard attempting to reduce the 70% software failure rate by creating a standard methodology for writing web applications. This development methodology works with any web application small and large. As the ColdFusion version has moved away from using custom tags, porting the techniques across to other languages has become that much simpler and far more elegant. In fact, the core techniques of Fusebox 3.0 should apply to the PHP version just as they do to the ColdFusion version.
