Question

I have a game that will display ten random cards based on number and suit, but I need to check an array to see if the card has already been displayed. But my local array $card is not being saved when it passes through the function. Here is all my code for right now please try running it and tell me what I am doing wrong if you want the images they are avaiable at.

here is my php:

    <?php
                                     //suit 1=Clubs | 2=Hearts | 3=Spades | 4=Diamonds//
                                     //Color 1=1or11 | 2-10=#   | 11-12=10//
$number;
$suit;
$card = array();

function newcard($number,$suit,$card){

$arrsuit = array (clubs, hearts, spades, diamonds);
$arrnumber = array (a, 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k);

$number = $arrnumber[rand(0,12)];                //Creates card value
$suit   = $arrsuit[rand(0,3)];       //Create card suit
$card   .= array  ($suit ." ". $number, hello);       //difines card name
return "<img src='cards/" . $suit . "-" . $number . "-150.png'/>";
}
for($i = 0; $i < 10; $i++){
echo newcard($number,$suit,$card);
}
echo $number;
foreach($card as $value){
    echo $value;
}


?>

To access a variable inside of a function use the follow techniques.

$GLOBALS['card'][] = array  ($suit ." ". $number, hello);

or

global $card;
$card[] = array  ($suit ." ". $number, hello);
