“usort” a Doctrine\Common\Collections\ArrayCollection?

Question

In various cases I need to sort a Doctrine\\Common\\Collections\\ArrayCollection according to a property in the object. Without finding a method doing that righ

Answer 1

Doctrine criteria does not allow to order by a property on a related object.

If you want to do it (like me), you have to use the uasort method of the Iterator like a previous response and if you use PHP 7, you can use the Spaceship operator <=> like this :

/** @var \ArrayIterator $iterator */
$iterator = $this->optionValues->getIterator();
$iterator->uasort(function (ProductOptionValue $a, ProductOptionValue $b) {
    return $a->getOption()->getPosition() <=> $b->getOption()->getPosition();
});

return new ArrayCollection(iterator_to_array($iterator));
