PHP：用户ID动态页面

Question

Hi I am making a website where the users can visit eachother. Therefore i need to make dynamic pages so that if i go to let's say...

www.mypage.net/user.php?id=32

Then i would end up on John Smiths profile, and show his profile. And if i went to id=54 then, my own profile would be shown. I was just wondering, how would i go forward on this? I already have the user id stored in a session when the user logs in, but how do i create the url so it looks like ?id=32 and not onlye user.php ?

Is there any good tutorials explaining this? Thx in advance!

I can already sense that you are gonna get lots of downvotes. That's because, you are not showing any effort and asking about stuff, that can be easily found on the net.

This is the basic of what you want:

$userid = (isset($_GET['uid']) ? $_GET['uid'] : NULL);

if ($userid) {
    $userinfo = $DB->query_first("SELECT * FROM `users` WHERE `id` = '$userid'");
    print_r($userinfo);
}

You can already see, that you need to read about $_GET and of course about mysql querying.

Further more, these types of concept related questions are more fit to Programmers. You should read SO's faq.
