You could check W3Schools' PHP guide, it has a lot of useful code snippets to do with cookies.
Depending what you are doing, you may also want to check out Sessions.

You can use the setcookie() function to store a cookie.

Example Code

//Check if cookie exists
if (isset($_COOKIE['uid'])) {
    //Get UID from cookie
    $uid = $_COOKIE['uid'];
} else {
    //Generate UID
    $uid = uniqid();
    //Store in cookie
    setcookie('uid',$uid);
}
