    A simple option would be to set a cookie through JavaScript and read it back with PHP.

    JavaScript

    Use the following function to make the cookie,

    function createCookie(name, value, days) {
    if (days) {
        var date = new Date();

        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));

        var expires = '; expires=' + date.toGMTString();
    } else {
        var expires = '';
    }
    document.cookie = name + '=' + value + expires + '; path=/; domain=.example.com';
}

    Don't forget to replace the domain=[...] URL part in the function.

    PHP

    echo $_COOKIE['YourCookieName'];

    Alternatively you could use AJAX to pass your variable to PHP.
