php 自动登录脚本_php利用cookie实现自动登录的方法

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:

enter password

后端PHP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!!!";

}

}

}

?>
