It defines everything necessary for the $Projectname application: Server variables, URL arguments, page structures, layouts, content, installed plugins, output device info, theme info, identity of the observer and (potential) page owner ... + We don't ever create more than one instance and always modify the elements of the single instance. The mechanics of this are somewhat tricky. If you have a function that is passed $a and needs to modify $a you need to declare it as a reference with '&' e.g. [code]function foo(&$a) { $a->something = 'x'; // whatever }; |
