㈠ php递归树形菜单

可以参考以下代码，但需要把你自己的数据库链接，表等改一下就可以了

<html>
<head>
<link href='style.css' rel=stylesheet>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script language="javaScript" src="TreeMenu.js"></script>
</head>
<body>
<?php
//基本变量设置
$GLOBALS["ID"] =1; //用来跟踪下拉菜单的ID号
$layer=1; //用来跟踪当前菜单的级数
//连接数据库
$Con=mysql_connect("localhost","root","1234");
mysql_select_db("wiki");
//提取一级菜单
$sql="SELECT * FROM wiki where pid=0";
$result=mysql_query($sql,$Con);
//如果一级菜单存在则开始菜单的显示
if(mysql_num_rows($result)>0) ShowTreeMenu($Con,$result,$layer,$ID);
//=============================================
//显示树型菜单函数 ShowTreeMenu($con,$result,$layer)
//$con：数据库连接
//$result：需要显示的菜单记录集
//layer：需要显示的菜单的级数
//=============================================
function ShowTreeMenu($Con,$result,$layer)
{
//取得需要显示的菜单的项目数
$numrows=mysql_num_rows($result);

//开始显示菜单，每个子菜单都用一个表格来表示
echo "<table cellpadding='0' cellspacing='0' border='0'>";
for($rows=0;$rows<$numrows;$rows++)
{
//将当前菜单项目的内容导入数组
$menu=mysql_fetch_array($result);
//提取菜单项目的子菜单记录集
$sql="select * from wiki where pid=$menu[cid]";
$result_sub=mysql_query($sql,$Con);
echo "<tr>";
//如果该菜单项目有子菜单，则添加JavaScript onClick语句
if(mysql_num_rows($result_sub)>0)
{
echo "<td width='20'><img src='folder.gif' border='0'></td>";
echo "<td class='Menu' onClick='javascript:ShowMenu(Menu".$GLOBALS["ID"].");'>";
}
else
{
echo "<td width='20'><img src='file.gif' border='0'></td>";
echo "<td class='Menu'>";
}
//如果该菜单项目没有子菜单，并指定了超级连接地址，则指定为超级连接，
//否则只显示菜单名称
//if($menu[url]!="")
//echo "<a href='$menu[cid]'>$menu[name]</a>";
//else
echo $menu['name'];
echo "
</td>
</tr>
";
//如果该菜单项目有子菜单，则显示子菜单
if(mysql_num_rows($result_sub)>0)
{
//指定该子菜单的ID和style，以便和onClick语句相对应
echo "<tr id=Menu".$GLOBALS["ID"]++." style='display:none'>";
echo "<td width='20'> </td>";
echo "<td>";
//将级数加1
$layer++;
//递归调用ShowTreeMenu()函数，生成子菜单
ShowTreeMenu($Con,$result_sub,$layer);
//子菜单处理完成，返回到递归的上一层，将级数减1
$layer--;
echo "</td></tr>";
}
//继续显示下一个菜单项目
}
echo "</table>";
}

php学生管理系统源码，供大家参考，具体内容如下

功能：

1.添加／删除／修改
2.数据存储.
界面分布：
index.php

add.php --->stu添加
action ---> sql中add/del/update
(处理html表单-->mysql的数据存储＆＆页面跳转)
edit.php --->stu修改
menu.php
-->首页

㈢如何用PHP根据用户权限，显示对应的菜单想找一下相关的例子，希望各路大佬多多指教

把菜单成一个数据库表，指定一个键。如：
id:1, title:文章管理, icon: document, url: admin/article/index (更多字段根据需要设置)
id:2, title:产品管理, icon: cube, url: admin/proct/index
id:3, title:系统设置, icon: setting, url: admin/setting/index
然后在管理员表中添加一个varchar(500) (长度根据你的菜单总数估计)或text字段
在管理员权限管理中列出所有菜单项，把id作为健值，选中的保存在管理员表的权限字段中
格式类似: 1,2,3
然后在输出菜单的时候进行权限判断
//将权限字段切割成数组
$perms = explode(',', $user['permission']);
foreach($menus as $menu){
if(in_array($perms, $menu['id'])){

echo '<a href="'. $menu['url'].'" >'.$menu['title'].'</a>';

}
}
然后在每个页面根据页面对应的权限id做一个判断
//比如在文章页面
if(!in_array($perms, 1)){
exit('没有权限');
}
以上是大体思路，具体根据你的系统设计编写代码并对应地优化。

㈣谁有详细php 下拉菜单代码

这是我自己用的一段代码，你自己改一下，点一下一级文本框，它所属的文本框会收起或伸展。
<SCRIPT language=javascript>

</SCRIPT>
<TABLE class=navi cellSpacing=1 align=center border=0>
<TBODY>
<TR>

<TH>后台 >> 新闻分类</TH></TR></TBODY></TABLE><BR>

<table border=0 cellspacing=1 align=center class=form>
<tr>
<th colspan="2">添加分类</th>
</tr>
<form action="" method="post">

<tr>
<td colspan="2" align="center" height='30'>

<select name="fid">
<option value="0">添加大类</option>
<?php
$query=$db->findall("shipin where fid=0");
while ($row=$db->fetch_array($query)){
$new_class_arr[$row[id]]=$row[name];
echo "<option value=\"$row[id]\">$row[name]</option>";
}

?>

</select>
<input type="text" name="name" value="">
<input type="submit" name="into_class" value="添加分类"/>

</td>
</form>
</tr>
</table>
<br>

<table border=0 cellspacing=1 align=center class=form>

<?php
