Using JavaScript variables as part of PHP

[jesso3]

Hello. I am new to PHP and learning the language. I have JavaScript variables on a .htm page. I have another page that is a .php. What I like to do is use a variable like say for instance: var time; and manipulate it in my PHP file. Can anyone show me how it is done? Thanks.
