OOP prob

[Anon]

Hi,

I m trying to use oop for my prog but I m getting some problems.

I have declare a class users to access data and store data in my database. I have definied methode to modifiy variable, to store 1 user in the database, to get 1 user, etc.. everything work fine until I want to work with more than 1 object.
I m trying to make a methode that return many users object from the db (like get_user_by_date_of_creation) and I don't know how to return an array of object or something like that.
Maybe I m using OOP in the wrong way but if you have idea help me!!

Thanks
Arnaud

I would create 2 classes : UsersCollection (represents all users, with methods such as add, count, delete, find),
UserObject (represents an instance of a user, with name, password, creation date properties and edit method).

In the UsersCollection class :
function aGetUsersByCreationDate($creationDate){
// SQL stuff to run query here

// Code to put results from query into array

return $array
}
I assume that the UserObject class has a constructor which allows you to pass a user reference and populate the class with the data from that user -

You can then build a page which does something like :

$colUsers = new UsersCollection;

$aUsers = $colUsers->aGetUsersByCreationDate("1 Jan 2000");

while (list($key, $value) = each($aUsers)){

$objUser = new UserObject($value)

echo "User name : " . $objUser->name;
}

Hope this helps...
