• [CodeQuality] Skip multiple assigns append before foreach on ForeachItemsAssignToEmptyArrayToAssignRector #4052

The following code should be skipped as well:

        $items2 = [];

        if (rand(0, 1)) {
            foreach (['foo', 'bar'] as $item) {
                $items2[] = $item;
            }
        }

        foreach ($items as $item) {
            $items2[] = $item;
        }
