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:
<html>
<head>
<title>enterpassword</title>
</head>
<body>
<formname="forml"method="post"action="cookiebasedpasswordlogin.php">
<table>
<tr>
<tdcolspan="2">
<divalign="center"><b>pleasespecifythepassword</b></div>
</td>
</tr>
<tr>>
<td>
<divalign="right">customerid</div>
</td>
<td>
<inputtype="text"name="username">
</td>
</tr>
<tr>
<td>
<divalign="right">password</div>
</td>
<td>
<inputtype="password"name="password">
</td>
</tr>
<tr>
<tdcolspan="2">
<center>
<inputtype="submit"name="submit"value="login">
</center>
</td>
</tr>
</table>
</form>
</body>
</html>后端PHP代码如下:
<?php
$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>lastlogintime:".$data[0]."</center></b><br>n";
echo"<b><center>currentdate:".$storetime."</center></b><br>n";
echo"<b><center>pageviewcount:".$data[l]."</center></b><br>n";
echo"<b><center>youhavesuccessfullyloggedin!</center></b>";
echo("<b><contor>youcanaccessthisareawithoutenteringapasswordforthenext24hours!</center></b>");
}else{
if(isset($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));
$url="location:cookieimp.php";
header($url);
}else{
echo"<hl><center>invalidpassword!!!</center></hl>";
}
}
}
?>
