[RESOLVED] Looping through two arrays to create one 2 Dimensional array

[SuPerNoVi]

Hi guys, I've been wrestling with this problem for a week now and I'm at the end of my tether.

Basically I've created a shop basket and I'm requesting all the Price and Quantity fields like so $PriceArray = $_REQUEST['Price']; they all have the same ID and have a square bracket containing the unique ProductID which successfully returns the two arrays populated with unique data (example below)...

Array ( [3] => 35 [5] => 60 [4] => 50 [2] => 25 )

The red value is my product ID and the blue is my Price value.
I have the same kind of array for the Quantity fields except the blue value is quantity instead of price.

So I've got two arrays $PriceArray and $QtyArray and from these I'm trying to create a 2D array like this...

array( array("ID" => "3", "Price" => "23", "Qty" => "4"), array("ID" => "4", "Price" => "54", "Qty" => "2"), array("ID" => "6", "Price" => "21", "Qty" => "10") )

I want this array so I can store it in the session easily and then have a confirmation page before inserting the data into the database. The user would also be able to go back and make amendments.

I also found this code on the forum that I thought might be modifiable to do what I want?

	function CustomMerge($a, $b)
	{
	   $result = array();
	   while(($key = each($a)) && ($val = each($b)))
	   {
		  $result[$key[1]] = $val[1];
	   }
	   return($result);
	} 

So can some of you clever folk please lend a hand, it'd be much appreciated.

Assumning your arrays are really equal in size and element-keys:

function mergethem($prices, $quantities)
  {
  $retval = array();
  foreach($prices as $key=> $price)
    {
    $retval[$key] => array(
    'price'=>$price,
    'quantity'=>$quantities[$key]);
    }
  return $retval
  }

Thanks for the quick reply I'm getting the following error though...

Parse error: syntax error, unexpected T_DOUBLE_ARROW in C:\Websites\Abyss Web Server\htdocs\mytimesheetsv2\shoporder.php on line 18

Line 18 is this line...

$retval[$key] => array('price' => $price, 'quantity' => $quantities[$key]);

Any ideas? I'm just passing the two arrays mentioned above.

yeah, typo:

$retval[$key] = array('price' => $price, 'quantity' => $quantities[$key]);

Sorry, I was being a bloody idiot. I was printing the array twice by accident... Doh!!

I got it working perfectly using the below code thanks to your help, much appreciated. You saved me a lot of stress, Thank You.

	function mergethem($prices, $quantities)
	{
	$retval = array();
	foreach($prices as $key => $price)
	{
		$retval[] = array('ID' => $key, 'Price' => $price, 'Quantity' => $quantities[$key]);
	}
	return $retval;
	}
