I have a theoretical question..
I know that you can get/read a PHP cookie with javascript by using: document.cookie
Is there a similar way to do this in PHP?
Can PHP get/read a cookie that is created i JavaScript? If yes, then how can you do that?

cookie php cannot assess the cookie, php can only assess cookie set by document.
Accessing Cookies with PHP Simplest way is to use either $_COOKIE or $HTTP_COOKIE_VARS variables. Following example will access all the cookies set in above example. You can use isset() function to check if a cookie is set or not.
A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user's computer. Each time the same computer requests a page with a browser, it will send the cookie too. With PHP, you can both create and retrieve cookie values.
A cookie is a piece of data from a website that is stored within a web browser that the website can retrieve at a later time. Cookies are used to tell the server that users have returned to a particular website.
You can use $_COOKIE, the superglobal. Just reference it like you would any array, where $_COOKIE['key_name'] is the cookie you want to access.
See the PHP API documentation.
