Calling Variables

So I need a little help understanding something here:

on Shirt. php I call <?php echo $product["img"]; ?> for example.

On the array it is under $products["img"], why does it work now on the singular form $product and not $products as it is declared on the array??

$products is a multidimensional array (an array containing multiple arrays). On line 5 of shirt.php it grabs the product array from $products with the product_id specified and sets that array to a variable called $product. From that point forward $product is referencing one single product and then you can call it's properties like name, img, etc.

Thank you for replying Ron. Its clear now

so $product = $products[$product_id], // Meaning that all the values under products[101] multidimensional array are now called from product.
