Send Cart information to php

I have a website in wordpress with woocommerce.
I need to get the total price of the items (items of the cart) in order to send via email with php.
I think 2 options:
– Save the information in a variable (var) php and then send it via email
– Get the content of a div which has a defined class and then send it via email
For example: Information of wordpress
TV Led u$s 300
Smartphone u$s 100
Total: u$s 400.-
I would like to received the information via email.
Can you help me please?
