how to count hits and unique IP?

hi all,
I want to track and save total hits that are done on my site.
I also want to save te unique IPs from which my site is being seen.
how can I do this using PHP.

I think there will be need to make a MYSQL database to save the hits and IPs,
how can I proceed in this?

Please solve my problem.

simple program / database
Mysql:

CREATE TABLE ip (ip VARCHAR(255) NOT NULL);



$ip = $_SERVER['REMOTE_ADDR'];
// connect to db
$query = mysql_query("SELECT * FROM ip WHERE ip='$ip';");
$result = mysql_fetch_array($query);
if (isset($result[ip]) || $result[ip] != $ip){
mysql_query("INSERT INTO ip (ip) VALUES ('$ip');");
