how do u use cookie to make sure that my visitors don't get the same random url twice?
this is my code:
$sql = "SELECT url FROM category order by vote limit 3";
$result = mysql_query ($sql);
$url = mysql_result($result,1,"url");
setcookie('url',$url,time()+60*60*5 );
print_r($_COOKIE); //debug only
if ($_COOKIE["url"]=="$url") {
$url = mysql_result($result,2,"url");
setcookie('url',$url,time()+60*60*5 );
echo $url;
}
this doesnt work 🙁
