首先是Index页面效果图

index.php

<?php
header('content-type:text/html;charset=utf-8');
date_default_timezone_set('PRC');
$filename="msg.txt";
$msgs=[];
//检测文件是否存在
if(file_exists($filename)){
  //读取文件中的内容
  $string=file_get_contents($filename);
  if(strlen($string)>0){
    $msgs=unserialize($string);
  }
}
?>

<div class="container-fluid">
    <div class="row-fluid">
        <div class="span12">
            <div class="page-header">
                <h1>
                    简易留言板-<span>V1.0</span>
                </h1>
            </div>
            <div class="hero-unit">

                <p>
                    这是一个可视化布局模板, 你可以点击模板里的文字进行修改, 也可以通过点击弹出的编辑框进行富文本修改. 拖动区块能实现排序.

                <p>
                    <a rel="nofollow" class="btn btn-primary btn-large" href="#">参看更多 »</a>
                </p>
            </div>
             <?php if(is_array($msgs)&&count($msgs)>0):?>
            <table class="table">
                <thead>
                    <tr>
                        <th>
                            编号
                        </th>
                        <th>
                            用户名

                            时间
                        </th>
                        <th>
                            内容
                        </th>
                        <th>
                            操作
                        </th>
                    </tr>
                </thead>
                <tbody>
                <?php $i=1;foreach($msgs as $key=>$val):?>
              <tr class="success">
              <td>
                <?php echo $i++;?>
              </td>
              <td>
                <?php echo $val['username'];?>
              </td>

              </td>
              <td>
                <?php echo date("m/d/Y H:i:s",$val['time']);?>
              </td>
              <td>
                <?php echo $val['content'];?>
              </td>
              <td>
                <a href="edit.php?id=<?php echo $key;?>">编辑</a>|<a href="#" onclick="show_confirm(<?php echo $key;?>)">删除</a>
              </td>
            </tr>
            <?php endforeach;?>
                </tbody>
            </table>
            <?php endif;?>
            <input type="button" class="btn btn-primary btn-lg" name="pubMsg" value="我要留言" onclick="window.location.href='add.php'"/>
        </div>
    </div>
</div>
<script type="text/javascript">
    function show_confirm(key){
        var r=confirm("确定删除吗？");
        if (r==true){
              location.href='delete.php?id='+key;
        }
    }
    </script>
</body>
</html>

然后是新增留言页面效果图

 

 

 

add.php

<?php
header('content-type:text/html;charset=utf-8');
date_default_timezone_set('PRC');
$filename="msg.txt";
$msgs=[];
//检测文件是否存在
if(file_exists($filename)){
  //读取文件中的内容
  $string=file_get_contents($filename);
  if(strlen($string)>0){
    $msgs=unserialize($string);
  }
}
//检测用户是否点击了提交按钮
if(isset($_POST['addMsg'])){
  $username=$_POST['username'];
  $title=strip_tags($_POST['title']);
  $content=strip_tags($_POST['content']);
  $time=time();
  //将其组成关联数组
  $data=compact('username','title','content','time');
  array_push($msgs,$data);
  $msgs=serialize($msgs);
  if(file_put_contents($filename,$msgs)){
    echo "<script>alert('留言成功！');location.href='index.php';</script>";
  }else{
    echo "<script>alert('留言失败！');location.href='index.php';</script>";
  }
}
?>

        </div>
    </div>
</div>

</html>

编辑留言页面

edit.php

<?php

date_default_timezone_set('PRC');
$filename="msg.txt";
$msgs=[];
$id=$_GET['id'];//获取id
