这篇文章主要介绍了php使用cookie实现记住用户名和密码实现代码,本文直接给出实现代码,需要的朋友可以参考下。

1. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
2. <form name="form1" method="post" action="check_remember.php">
3. <table width="300" align="center" cellpadding="0" cellspacing="0">
4. <thead>
5. <tr>
6. <td colspan="2" align="center"><b>记住用户名和密码</b></td>
7. </tr>
8. </thead>
9. <tr align="center">
10. <td>用 户 名：</td>
11. <td><input type="text" value="<?php echo $_COOKIE['name'];?>" name="name"></td>
12. </tr>
13. <tr align="center">
14. <td>密码：</td>
15. <td><input type="password" name="password" value="<?php echo $_COOKIE['password']?>"></td>
16. </tr>
17. <tr align="center">
18. <td>记住用户名和密码</td>
19. <td><?php if($_COOKIE['remember'] == 1){?><input type="checkbox" name="remember" value="1" checked><?php }else{($_COOKIE['remember'] == "")?><input type="checkbox" name="remember" value="1"><?php }?></td>
20. </tr>
21. <tr align="center">
22. <td colspan="2"><input type="submit" name="Submit" value="提交" /></td>
23. </tr>
24. </table>
25. </form>
26. check_remember.php
27. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
28. <?php
29. $name = $_POST['name'];
30. $password = $_POST['password'];
31. $remember = $_POST['remember'];
32. if($remember == 1){
33. setcookie('name',$name,time()+3600);
34. setcookie('password',$password,time()+3600);
35. setcookie('remember',$remember,time()+3600);
36. }else{
37. setcookie('name',$name,time()-3600);
38. setcookie('password',$password,time()-3600);
39. setcookie('remember',$remember,time()-3600);
40. }
41. echo "<a href=\"remember.php\">返回</a>";
42. ?>
