Hello,

I would like to know if someone can explain to me some of the code that user "job0107" used for declaring some variables from post #23. Part of it is shown below. It's part of the code for the function called showCart() within the ShoppingCart Class on ShoppingCart.php.

I don't understand how the following declarations works, or what they mean. How is the notation $ProdID = $Order[0] ? $Order[0] : ""; read, or what does it mean?
What does the "?" and the ":" represent?
I've tried searching for the meaning online. But can't find anything, or just don't know how to Google for it.

I know that the way it's written WORKS properly and that the variables do print out the correct TABLE name and product ID. I just want to know why.

Once the multidimensional array $Orders is broken down,
Why can't we just declare the following:
$Table_Name = $Order[1];
$ProdID = $Order[0];

Thanks for the help!

PHP Code:

$sw = 0;
       for($i=0;$i<count($this->Orders);$i++) {
          $Order = $this->Orders[$i];
          $Table_Name = $Order[1] ? $Order[1] : "";
          echo "$Table_Name<br />";
          $ProdID = $Order[0] ? $Order[0] : "";
          $OrderQTY = 1;
          if($Table_Name && $ProdID) {
             if($sw == 0) {
                echo "<table width='100%' border='1'><tr><th>Remove Item</th><th>Product</th><th>Quantity</th><th>Price Each</th></tr>";
                $sw = 1;
             }
