php利用cookie实现自动登录的方法_php技巧

本文实例讲述了php利用cookie实现自动登录的方法。分享给大家供大家参考。具体实现方法如下：

html前端页面代码如下:

>

please specify the password
customer id
password

后端PHP代码如下:

$now = getdate();
$storetime= $now["weekday"] . " " . $now["month"] ." " . $now["year"] ;
$storetime.=" time : ";
if ($now["hours"] $storetime.= "0" . $now["hours"];
} else {
$storetime.= $now["hours"];
}

$storetime.= ":";
if ($now["minutes"] $storetime.= "0" . $now["minutes"];
} else {
$storetime.= $now["minutes"];
}

$storetime.= ": ";
if ($now["seconds"] $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!!!";
}
}
}
?>
