SplDoublyLinkedList::bottom — Peeks at the node from the beginning of the doubly linked list
SplDoublyLinkedList::__construct — Constructs a new doubly linked list
SplDoublyLinkedList::count — Counts the number of elements in the doubly linked list.
SplDoublyLinkedList::current — Return current array entry
SplDoublyLinkedList::getIteratorMode — Returns the mode of iteration
SplDoublyLinkedList::isEmpty — Checks whether the doubly linked list is empty.
SplDoublyLinkedList::key — Return current node index
SplDoublyLinkedList::next — Move to next entry
SplDoublyLinkedList::offsetExists — Returns whether the requested $index exists
SplDoublyLinkedList::offsetGet — Returns the value at the specified $index
SplDoublyLinkedList::offsetSet — Sets the value at the specified $index to $newval
SplDoublyLinkedList::offsetUnset — Unsets the value at the specified $index
SplDoublyLinkedList::pop — Pops a node from the end of the doubly linked list
SplDoublyLinkedList::prev — Move to previous entry
SplDoublyLinkedList::push — Pushes an element at the end of the doubly linked list
SplDoublyLinkedList::rewind — Rewind iterator back to the start
SplDoublyLinkedList::serialize — Serializes the storage
SplDoublyLinkedList::setIteratorMode — Sets the mode of iteration
SplDoublyLinkedList::shift — Shifts a node from the beginning of the doubly linked list
SplDoublyLinkedList::top — Peeks at the node from the end of the doubly linked list
SplDoublyLinkedList::unserialize — Unserializes the storage
SplDoublyLinkedList::unshift — Prepends the doubly linked list with an element
