php中的数组数组？

Question

I have an N amount of products with an n amount of properties.

How exactly could I use a for each inside a for each to get the properties of each product? Is it by storing an array in an array or something?

Thanks

$products = array(
    array('name' => 'Product 1', 'color' => 'red', 'size' => 'large'),
    array('name' => 'Product 2', 'color' => 'blue', 'size' => 'medium'),
    array('name' => 'Product 3', 'color' => 'green', 'size' => 'small')
);

foreach ($products as $product) {
  foreach ($product as $property => $value) {
    echo $property . " = " . $value . ",";
  }
  echo "<br />";
}
