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:复制代码 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:复制代码 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>"; } } } ?>
希望本文所述对大家的PHP程序设计有所帮助。
