Core libraries are of course first candidate for OOP, but I think there are many other places where you can use it successfully. Take for instance how it is used in TemplateTamer. In it, you define a class responsible for the generation of the page. In typicall usage you have a common class that all page classes inherit from, and which defines elements of page common to all pages on the site, and specific page classes implement only the parts they differ in. When the site grows, it is common to refine the hierarchy of page classes, so you have one page class on the top, then a few below it describing main sections of the site, and then on the bottom concrete page classes. Another OOP usage in TT can be in creating classes that represent GUI components. For instance on one site I have worked, I have created a JobAdForm object, that handles for reponsible displaying form and editing of JobAd object. Than when I needed similar but litle more extended version for superuser pages, I have just created a subclass SuperuserJobAdForm, and overided necessary parts, but inhertied 95% of code. So I think there is usage for OOP also in "gui" parts of the code, where it can also help better organization of code, and reuse between the pages or components on the same site. rush -- http://www.templatetamer.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
