$now = getdate();
$storetime= $now["weekday"] . " " . $now["month"] ." " . $now["year"] ;
$storetime.=" time : ";
if ($now["hours"] < 10) {
$storetime.= "0" . $now["hours"];
} else {
$storetime.= $now["hours"];
}
$storetime.= ":";
if ($now["minutes"]<10) {
$storetime.= "0" . $now["minutes"];
} else {
$storetime.= $now["minutes"];
}
$storetime.= ": ";
if ($now["seconds"] <10) {
$storetime.= "0" . $now["seconds"];
} else {
$storetime.= $now["seconds"];
}
if (isset($data)) {
$counter=++$data[l];
setcookie("data[0]",$storetime,time() + (60*60*24));
setcookie("data[l]", $counter,time() + (60*60*24)); setcookie("data[2]",$username,time() + (60*60*24));
echo "<b><center>hi " . $data[2] . " ! !</center></b><br>n";
echo "<b><center>last login time :" .$data[0] . "</center></b><br>n";
echo "<b><center>current date :" .$storetime. "</center></b><br>n";
echo "<b><center>page view count :" . $data[l]. "</center></b><br>n";
echo "<b><center>you have successfully logged in!</center></b>";
echo ("<b><contor>you can access this area without entering a password for the next 24 hours!</center></b>");
} else {
if (isset($username) && isset($password)) {
if ($password=="superpass") {
$counter=0;
setcookie("data[0]",$storetime,time() + (60*60*24));
setcookie("data[l]",$counter,time() + (60*60*24));
setcookie("data[2]",$username,time() + (60*60*24));
