Needing PHP Help with Custom emails

Hi there,

I’m creating my custom emails and stuck on the PHP parts to show customers usernames, emails, orders and all kind. By any chance, I could know the PHP for this as there is no real support on this unless we purchase a plugin for this. I’m not sure why woocommerce don’t have this list, as it would be very helpful if you are customizing your own woocommerce email. Thanks for reading this and the help again
