Iterate Doctrine Collection ordered by some field

Question

I need something like this:

        $products = Products::getTable()->find(274);
        foreach ($products->Categories->orderBy(\'title\') as $category

I was just looking at the same problem. You need to convert the Doctrine_Collection into an array:

$someDbObject = Doctrine_Query::create()...;
$children = $someDbObject->Children;
$children = $children->getData(); // convert from Doctrine_Collection to array

Then you can create a custom sort function and call it:

// sort children
usort($children, array(__CLASS__, 'compareChildren')); // fixed __CLASS__

Where compareChildren looks something like:

private static function compareChildren($a, $b) {
   // in this case "label" is the name of the database column
   return strcmp($a->label, $b->label);
}
