Symfony 3 - difference between 2 arraycollection

Question

Is there a way to differentiate 2 ArrayCollection ? (like array_diff)

today I loop on the first and check if $it->contains() match, but I think it can be refactored.

Answer 1

You can use array_diff in the following way:

$diff = array_diff($arrayCollection1->toArray(), $arrayCollection2->toArray());

$arrayCollectionDiff = new ArrayCollection($diff);
