  // Now the two-dimensional $cars array contains four arrays,

  // To get access to the elements of the $cars array we must point
  // to the two indices (row and column):
  echo $cars[0][0].": In stock: ".$cars[0][1].", sold: ".$cars[0][2].".
\n";
  echo $cars[1][0].": In stock: ".$cars[1][1].", sold: ".$cars[1][2].".

  echo $cars[2][0].": In stock: ".$cars[2][1].", sold: ".$cars[2][2].".
\n";
  echo $cars[3][0].": In stock: ".$cars[3][1].", sold: ".$cars[3][2].".
