Email field variable in PHP

[KostasAM]

Hello,

I am trying to make a checkbox in the checkout page where the user can opt in in order to receive emails. Problem is i know nothing about PHP. So after watching a couple of tutorials i made a checkbox. I would like to know how to get the email variable from the user mandatory fields when they complete their order. I haven't figured what i should do with the variable yet, i would just like to know how to get their email if the checked the checkbox. I hope this makes sense.
