Non-Array Iterables Collection

\VersatileCollections\NonArrayIterablesCollection is a Collection class that only accepts items that are objects for which \is_iterable returns true.

NOTE: this collection will not accept items that are arrays (because an array is not an object, even though it is an iterable).

Example Usage:

    
    $collection = new \VersatileCollections\NonArrayIterablesCollection(
                    new \ArrayObject(),
                    new \SplDoublyLinkedList(),
                    new \SplStack(),
                    new \SplQueue(),
                    new \SplMaxHeap(),
                    new \SplMinHeap(),
                    new \SplPriorityQueue(),
                    new \SplFixedArray(),
                    new \SplObjectStorage()
                );

    // OR
    
    $collection = \VersatileCollections\NonArrayIterablesCollection::makeNew([
                    new \ArrayObject(),
                    new \SplDoublyLinkedList(),
                    new \SplStack(),
                    new \SplQueue(),
                    new \SplMaxHeap(),
                    new \SplMinHeap(),
                    new \SplPriorityQueue(),
                    new \SplFixedArray(),
                    new \SplObjectStorage()
                ]);

    // OR

    $collection = new \VersatileCollections\NonArrayIterablesCollection();
    $collection[] = new ArrayObject();
    $collection[] = new SplDoublyLinkedList();
    $collection[] = new SplStack();
    $collection[] = new SplQueue();
    $collection[] = new SplMaxHeap();
    $collection[] = new SplMinHeap();
    $collection[] = new SplPriorityQueue();
    $collection[] = new SplFixedArray();
    $collection[] = new SplObjectStorage();

Use this type of collection if you want to only store objects (except php arrays) that are iterable.

You can even extend it and add other features in your extended class.
