Which of the following tutorials about zendframework is provided by zendframework? on the Internet, most of them are preliminary configurations. I didn't talk about how to define the business logic of models. for example, I want to have a bbs file in models and define a bbs class, the method is just show (). if I want to access the show method of BBS in the Action in controllers, is it a tutorial of zendframework?
Zendframework, the initial configurations on the Internet are mostly described. I didn't talk about how to define the models business logic,

For example, if I want to have a bbs file in models and define a bbs class, the method is show (). if I want to access the BBS show method in the Action in controllers, is the class in the model inherited? it cannot be accessed directly. Reading the book seems to say something to extends Table_Db, but my project does not use a database for the time being and does not need a database.
