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         


        

Answer 1

You could use collection iterator:

$collection = Table::getInstance()->findAll();

$iter = $collection->getIterator();
$iter->uasort(function($a, $b) {
  $name_a = (int)$a->getName();
  $name_b = (int)$b->getName();

  return $name_a == $name_b ? 0 : $name_a > $name_b ? 1 : - 1;
});        

foreach ($iter as $element) {
  // ... Now you could iterate sorted collection
}

If you want to sort collection using __toString method, it will be much easier:

foreach ($collection->getIterator()->asort() as $element) { /* ... */ }
