How to get product category in Woo-commerce?

To get Category of the product is very easy. We have to get all categories related to Woo-commerce products. To do this WordPress function get_terms( ) is used. Following detail of this WordPress function is given:

string|array $args = array(), array $deprecated = '' ); 
?>

So in get_terms accept string or array in first argument. To get all categories related to posts we put post_tag, But we have to take all categories related to products so instead of ‘post_tags‘ we will insert ‘product_cat‘.

 false,
) ); 
?>

By using this argument we get all categories related to product categories. We will get array of all categories.
