[RESOLVED] Random Numbers

I'm pulling my hair, I'm just creating a bunch of different little experiments and little fun projects right now. I've got a Deal or No Deal thing that's going very well. I'm trying to create some XML/PHP dealies. And my last one is the where I hit a snag. I'm trying to create a Black Jack game, but my random number generator doesn't seem to be working right. Here's my code: {it's completely unfinished and I only started creating it.}

PHP Code:

---

session_start();

if(!isset($_SESSION['suite'])){    
          $_SESSION['suite'] = array("Hearts", "Diamonds", "Clubs","Spades");
}

if(!isset($_SESSION['number']))
{    
          $_SESSION['number'] = array("Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten",    "Jack", "Queen", "King", "Ace");
}

if(!isset($_SESSION['cards']))
{    
          $_SESSION['cards'];
}

function showCard()
{
          $suite = $_SESSION['suite'][rand(0, 3)];
          $number = $_SESSION['number'] [rand(0, 12)];
          return $number .' of '. $suite;
}

function addToCardsArray($card){    
          $_SESSION['cards'][] = $card;
}

echo '<form action="mypage.php">';
echo showCard() .'<br>';
echo showCard();
echo '</form>'; 


---

The reason I say it doesn't work is that everytime I refresh my page, it returns the same card. Every once in a while it changes, but that happens after a minute or so, so it's not helpful at all.

Indent your code, then we'll talk.

Hopefully that's indented better.

well for 1, this isnt doing anything:

PHP Code:

---

if(!isset($_SESSION['cards']))
{    
          $_SESSION['cards'];
} 


---

or this:

PHP Code:

---

function addToCardsArray($card){    
          $_SESSION['cards'][] = $card;
} 


---

EDIT:
I tested your code, and it works just fine...

Cards is going to be a Session variable that keeps which cards have been played, so if a card is on the list, then a function would get a new card.

well the top one still doesnt do anything. and did you see my link?

Yep, I saw it. I added a submit button to the page. That should refresh the page when I press it. I'm going to see if that works.

That function:

Code:

---

function addToCardsArray($card)
{   
          $_SESSION['cards'][] = $card;
}

---

is supposedly to take a value and add the value onto the SESSION array. So it goes from 0 values to 1 value and so on. At least that's what I'm hoping.

Edit: The post and submit button work. It gets new values. Good idea, I was hoping that just simply refreshing the page would work, but apparently not.
