Remove Items if exists in another collection

I've two collection.

$collection1  = [
    'id' => 1, 
    'id' => 2,
    'id' => 3
];

$collection2  = [
    'id' => 7, 
    'id' => 2,
    'id' => 4
];

I want to remove items from $collection1 if an item is exists in $collection2.

In that case, item with id 2 would be removed.
