php如何实现记住密码的功能

使用cookie记住密码：

remember.php
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<form id="form1" name="form1" method="post" action="check_remember.php">
<table width="300" border="1" align="center" cellpadding="0" cellspacing="0">
<thead>
  <tr> 
    <td colspan="2" align="center"><b>记住密码</b></td> 
  </tr>
</thead>   
  <tr align="center">
    <td>用 户 名：</td>
    <td><input type="text" value="<?php echo $_COOKIE['name'];?>" name="name"></td>
  </tr>
  <tr align="center">
    <td>用户密码：</td>
    <td><input type="password" name="password" value="<?php echo $_COOKIE['password']?>"></td>
  </tr>
  <tr align="center">
    <td>记住密码</td>
    <td><?php if($_COOKIE['remember'] == 1){?><input type="checkbox" name="remember" value="1" checked><?php }else{($_COOKIE['remember'] == "")?><input type="checkbox" name="remember" value="1"><?php }?></td>
  </tr>
  <tr align="center">
    <td colspan="2"><input type="submit" name="Submit" value="提交" /></td>
  </tr>
</table>
</form>

check_remember.php
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php
    $name = $_POST['name'];
    $password = $_POST['password'];
    $remember = $_POST['remember'];
    if($remember == 1){
        setcookie('name',$name,time()+3600);
        setcookie('password',$password,time()+3600);
        setcookie('remember',$remember,time()+3600);
    }else{
        setcookie('name',$name,time()-3600);
        setcookie('password',$password,time()-3600);
        setcookie('remember',$remember,time()-3600);
    }
    echo "<a href=\"remember.php\">返回</a>";
