[PHP]prosty quiz z danych z tablicy Opcje

[greg606]

Witam próbuję napisać prosty quiz który pytania bierze z tablicy.
Mam problem z napisaniem obsługi odpowiedzi: "Wiem" Zakładam, że po tej odpowiedzi pytanie ma zostać usunięte z tabeli.
I tu pojawia się problem
Proszę o poradę jak to rozwiazać

	public function indexAction() {
		$item = new Knowledge_Model_Item ();
		$items = $item->fetchAll ();
		$itemscount = count ( $items );
		$request = $this->getRequest ();
 
		if ($request->getParam ( "itemnumber" )) {
 
			$itemnumber = $request->getParam ( "itemnumber" );
 
			//handling correct answers
			if ($request->getParam ( "yes" )) { //2
 
 
				unset ( $items [$itemnumber] ); // unset($items [2]) 
				$items = array_values ( $items );
				// array with no [2]
				$itemscount = count ( $items );
 
				if ($itemnumber > $itemscount) {
					echo "no more items";
 
				}
			}
 
			//handling end of items
			if ($itemnumber >= $itemscount) {
				$itemnumber = 0;
			}
 
		} else {
			//handling first item
			$itemnumber = 0;
		}
 
		//setting view variables
		$this->view->item = $items [$itemnumber];
		$this->view->itemnumber = $itemnumber + 1;
		$this->view->itemscount = $itemscount;
		$this->view->itemsleft = $itemscount - $itemnumber;
