    <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">

     </tr>
     <tr align="center">
     <td>密码：</td>
     <td><input type="password" name="password" value="<?php echo $_COOKIE['password']?>"></td>
     </tr>
     <tr align="center">
     <td>记住用户名和密码</td>
     <td><?php if($_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>
