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,
	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. . .  Dusty
