Multi-dimensional array question

[Harley1979]

Hello,

 

Programing really isn't my strongest point so I'm after a little help here with something.

 

I am writting a simple shopping cart, what I specifically need to know is this.

 

If I write two id's into a multi-dimensional array;

 

$_SESSION['productItem'] = $productItem;
$_SESSION['productSize'] = $productSize;

$productItem .= ','.$_REQUEST['itemID'];
$productSize .= ','.$_REQUEST['sizeID'];

$myArray = ($productItem, $productSize);

 

How can I extract and seperate $productItem and $productSize again?

 

The sizes are pulled from a seperate table in the database so it is important that I'm able to extract the $productSize array for this functionality.

 

How would I best approach this?

 

Thanks

The code you've posted doesn't create a multidimensional array.

If I understand you correctly.

 

Change your line to:

 

$myArray = array($productItem, $productSize);

 

Then read with $myArray[0] or $myArray[1].

 

For example:

 

<?php

$_SESSION['productItem'] = $productItem;
$_SESSION['productSize'] = $productSize;

$productItem .= ','.$_REQUEST['itemID'];
$productSize .= ','.$_REQUEST['sizeID'];

$myArray = array($productItem, $productSize);

//To test
echo "Item ".$myArray[0]." and size ".$myArray[1];

?>

Meant to add.. which yes isn't multidimensional but I don't see where that is needed. There is only 2 items appearing once? Why is an array even needed?
