㈠ php遞歸樹形菜單

可以參考以下代碼，但需要把你自己的資料庫鏈接，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
//基本變數設置
$GLOBALS["ID"] =1; //用來跟蹤下拉菜單的ID號
$layer=1; //用來跟蹤當前菜單的級數
//連接資料庫
$Con=mysql_connect("localhost","root","1234");
mysql_select_db("wiki");
//提取一級菜單
$sql="SELECT * FROM wiki where pid=0";
$result=mysql_query($sql,$Con);
//如果一級菜單存在則開始菜單的顯示
if(mysql_num_rows($result)>0) ShowTreeMenu($Con,$result,$layer,$ID);
//=============================================
//顯示樹型菜單函數 ShowTreeMenu($con,$result,$layer)
//$con：資料庫連接
//$result：需要顯示的菜單記錄集
//layer：需要顯示的菜單的級數
//=============================================
function ShowTreeMenu($Con,$result,$layer)
{
//取得需要顯示的菜單的項目數
$numrows=mysql_num_rows($result);

//開始顯示菜單，每個子菜單都用一個表格來表示
echo "<table cellpadding='0' cellspacing='0' border='0'>";
for($rows=0;$rows<$numrows;$rows++)
{
//將當前菜單項目的內容導入數組
$menu=mysql_fetch_array($result);
//提取菜單項目的子菜單記錄集
$sql="select * from wiki where pid=$menu[cid]";
$result_sub=mysql_query($sql,$Con);
echo "<tr>";
//如果該菜單項目有子菜單，則添加JavaScript onClick語句
if(mysql_num_rows($result_sub)>0)
{
echo "<td width='20'><img src='folder.gif' border='0'></td>";
echo "<td class='Menu' onClick='javascript:ShowMenu(Menu".$GLOBALS["ID"].");'>";
}
else
{
echo "<td width='20'><img src='file.gif' border='0'></td>";
echo "<td class='Menu'>";
}
//如果該菜單項目沒有子菜單，並指定了超級連接地址，則指定為超級連接，
//否則只顯示菜單名稱
//if($menu[url]!="")
//echo "<a href='$menu[cid]'>$menu[name]</a>";
//else
echo $menu['name'];
echo "
</td>
</tr>
";
//如果該菜單項目有子菜單，則顯示子菜單
if(mysql_num_rows($result_sub)>0)
{
//指定該子菜單的ID和style，以便和onClick語句相對應
echo "<tr id=Menu".$GLOBALS["ID"]++." style='display:none'>";
echo "<td width='20'> </td>";
echo "<td>";
//將級數加1
$layer++;
//遞歸調用ShowTreeMenu()函數，生成子菜單
ShowTreeMenu($Con,$result_sub,$layer);
//子菜單處理完成，返回到遞歸的上一層，將級數減1
$layer--;
echo "</td></tr>";
}
//繼續顯示下一個菜單項目
}
echo "</table>";
}
?>

1.添加／刪除／修改
2.數據存儲.
界面分布：
index.php

add.php --->stu添加
action ---> sql中add/del/update
(處理html表單-->mysql的數據存儲＆＆頁面跳轉)
edit.php --->stu修改
menu.php
-->首頁

㈢如何用PHP根據用戶許可權，顯示對應的菜單想找一下相關的例子，希望各路大佬多多指教

把菜單成一個資料庫表，指定一個鍵。如：
id:1, title:文章管理, icon: document, url: admin/article/index (更多欄位根據需要設置)
id:2, title:產品管理, icon: cube, url: admin/proct/index
id:3, title:系統設置, icon: setting, url: admin/setting/index
然後在管理員表中添加一個varchar(500) (長度根據你的菜單總數估計)或text欄位
在管理員許可權管理中列出所有菜單項，把id作為健值，選中的保存在管理員表的許可權欄位中
格式類似: 1,2,3
然後在輸出菜單的時候進行許可權判斷
//將許可權欄位切割成數組
$perms = explode(',', $user['permission']);
foreach($menus as $menu){
if(in_array($perms, $menu['id'])){

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

}
}
然後在每個頁面根據頁面對應的許可權id做一個判斷
//比如在文章頁面
if(!in_array($perms, 1)){
exit('沒有許可權');
}
以上是大體思路，具體根據你的系統設計編寫代碼並對應地優化。

㈣誰有詳細php 下拉菜單代碼

這是我自己用的一段代碼，你自己改一下，點一下一級文本框，它所屬的文本框會收起或伸展。
<SCRIPT language=javascript>
