MVC: Best Way to Query Related Tables

I've been programming procedural code for quite some time, and recently I've been learning MVC. I have tried a couple of frameworks and decided I wanted to write my own from scratch to learn it inside and out. So far I have a working MVC framework (and it works great!) but I'm trying to determine the best way to query related tables.

As of now, in my member model, I use the following to get a list of the members and their rank_name

SELECT m.*, r.`name` AS rank_name
FROM `{$this->table}` AS m
LEFT JOIN `ranks` AS r
    ON r.`id` = m.`rank_id`

This works fine, but it does not seem like the way it's supposed to be done in MVC. After working with frameworks like cakephp, I know that member hasOne rank (or is it rank hasMany member?)

The only alternative I thought of was to query the members table by itself in the member model, and then call a method in the rank model to get the rank name for each row, like this:

// member model
SEL开发者_StackOverflow社区ECT *
FROM `{this->table}`

while($row = $result->fetch_assoc()) {
    $data []= $row;
    $data['rank_name'] = $this->Rank->get_name($row['rank_id']);
}

But this can't be very efficient, having to run a separate query for each member. The only other concept I thought of was using MySQL's IN(x, y, z) function to get the rank names and then merging the arrays somehow.

What is the best practice for this in MVC?

Maybe an ORM (object relational mapper) is what you're looking for. An ORM assists you in storing and retrieving your modelobjects from the database.

For PHP I guess your best choice is Doctrine.
