Some compatibility problems were reported following the release of SLOODLE 1.0, and they largely appear to centre around the object-oriented plugin system I developed for the Presenter module. The idea is fairly simple. The SLOODLE core team or 3rd party developers can create plugin classes to extend the module’s functionality. These will all belong to a structured inheritance hierarchy, and will be automatically detected and loaded by the SLOODLE framework. However, it has been a big challenge maintaining compatibility for both PHP4 and PHP5 because the object orientated features of the language have changed so much in that time.
I think I’ve finally found the solution, and it’s infuriatingly inelegant. Read more PHP4/5: Object orientation and compatibility
