i made this script that add in a mysql database information about who have visited my website.\[code\]session_start()if(!isset($_SESSION['log'])) { $ip=$_SERVER['REMOTE_ADDR']; $date=date("Y-m-d H:i:s"); $browser=$_SERVER['HTTP_USER_AGENT']; $browser=mysql_real_escape_string($browser); if(isset($_SESSION['nickname'])) { $user=$_SESSION['nickname']; } else { $user="unknownABCD1234"; } $insert=mysql_query("INSERT INTO views (ip, user, date, browser) VALUES ('$ip', '$user', '$date', '$browser')", $mydb); $_SESSION['log']='logged'; $_SESSION['iplog']=$ip; $_SESSION['datelog']=$date;}\[/code\]the problem is that it adds the referencee for each user many times (but not ever, just sometimes). example, i find on my db infos like these :\[code\]ID: 1IP : 95.108.244.252USER : unknownABCD1234 DATE : 2010-08-07 01:16:00BROWSER : Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots)ID : 2 IP : 95.108.244.252 USER : unknownABCD1234 DATE : 2010-08-07 01:16:04BROWSER : Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots)\[/code\]that's impossible no? i sure that the session during more than 4 seconds
