woocommerce-how can i get all products by their groups! [closed]

i think this is what you need:

$args = array(
'orderby'    => 'name',
'hide_empty' => 1
);
$category_terms = get_terms( 'product_cat', $args );

foreach($category_terms as $cat_term){

echo $cat_term->name;
}

btw: woocommerce is offtopic here!
