date_default_timezone_set('prc');
$filename="msg.txt";
$msgs=[];
//检测文件是否存在
if(file_exists($filename)){

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>
用户名
</th>
<th>
标题
</th>
<th>

<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>
<?php echo $val['title'];?>
</td>
<td>
<?php echo date("m/d/y h:i:s",$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>";
}
}
?>
