这篇文章主要介绍了php利用cookie实现自动登录的方法,涉及针对cookie的读取判断及登陆操作,是非常实用的技巧,需要的朋友可以参考下
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>enter password</title>
- </head>
- <body>
- <form name="forml" method="post" action="cookiebasedpasswordlogin.php">
- <table>
- <tr>
- <td colspan="2" >
- <div align="center"><b>please specify the password</b></div>
- </td>
- </tr>
- <tr>>
- <td>
- <div align="right">customer id</div>
- </td>
- <td>
- <input type="text" name="username">
- </td>
- </tr>
- <tr>
- <td>
- <div align="right">password</div>
- </td>
- <td>
- <input type="password" name="password">
- </td>
- </tr>
- <tr>
- <td colspan="2">
- <center>
- <input type="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 " . $data[2] . " ! !</center></b><br>n";
- echo "<b><center>last login time :" .$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));
- $url="location: cookieimp.php";
- header($url);
- }else{
- echo "<hl><center>invalid password!!!</center></hl>";
- }
- }
- }
- ?>
