Re: Silly OOP question

I've always wondered this about OOP and maybe you guys can answer this question. I'm writing a php application and I'm trying to figure out the correct way to right the oop part of this application. for instance. I have a "project.class" file that has functions for dealing with individual projects because you break down ideas into singular entities in OOP(as I understand it) But what if I wanted to deal with multiple projects such as getting a list of the projects in my database, should I create a function in the "project.class" to handle the now plural request, or should I create a "projects.class" file that has a function called "getProjects". Hopefully I'm explaining this question right. It makes sense in my own head. :-) Thanks, Brent Brent,

there are many ways so skin a cat, but one way to solve your problem in an OO manner would be a container class, call it projects or what you will. An example(not tested) could be: <?php class Container { private projects = array(); // Contains projects private projectsLoaded = false; ... other methods ... public function getProjects() { if (!$this->projectsLoaded) { $this->loadProjects(); } return $this->projects; } private function loadProjects() { //code to load the projects into the project array $this->projectsLoaded = true; } } ?> In your main code you can have something like: $container = new Container; foreach($container->getProjects as $project) { $something = $project->someMethod(...); ... ... } Hope this helps. . .
