后端PHP代码如下:
复制代码 代码如下:     $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 "

hi " . $data[2] . " ! !
n";
        echo "last login time :" .$data[0] . "
n";
        echo "current date :" .$storetime. "
n";
        echo "page view count :" . $data[l]. "
n";
        echo "you have successfully logged in!";
        echo ("you can access this area without entering a password for the next 24 hours!");
   } else {
    if (isset($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));
          $url="location: cookieimp.php";
          header($url);
     }else{
          echo "invalid password!!!";
     }
