本篇文章主要介绍php中的权限管理，感兴趣的朋友了解下，希望可以帮到大家。

php-人员权限管理（RBAC）

权限管理可以想做vip的功能，普通用户和vip用户的功能是不一样的，大致会用到五张表：用户表、角色表、功能表，还有他们之间互相关联的表：用户与角色表、角色与功能表

我用到的五张表如下：

一.首先写的是管理员页面

1.用下拉列表显示用户名

<p></p>

<select id="</code"><code class="php string" style="margin:0px!important; padding:0px!important; background:none!important; border:0px!important; bottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.8em!important; outline:0px!important; overflow:visible!important; position:static!important; right:auto!important; top:auto!important; vertical-align:baseline!important; width:auto!important; font-family:Consolas," bitstream vera sans mono new min-height:auto color:blue>"user">

<?php

require"../DBDA.class.php";

$db = new DBDA();

$sql = "select * from users";

$arr = $db->query($sql,1);

foreach($arr as $v)

{

echo"<option value="'{$v[0]}'">{$v[2]}</option>";

}

?>

2.因为上面已经造了新对象，所以在显示角色名时直接从SQL语句开始写

<p>请选择角色：</p><div class="aritcle_card flexRow"> <div class="artcardd flexRow"> <a class="aritcle_card_img" href="/xiazai/code/11227" title="商城购物系统"><img src="https://img.php.cn/upload/webcode/000/000/010/176541481284803.png" alt="商城购物系统" onerror="this.onerror='';this.src='/static/lhimages/moren/morentu.png'" ></a> <div class="aritcle_card_info flexColumn"> <a href="/xiazai/code/11227" title="商城购物系统">商城购物系统</a> <p>商城购物系统是一个以php+MySQL进行开发的可塑性极强的电子商品平台；商城购物系统可自定义商品栏目内容，包含分销功能，分销管理、分销订单提成完整功能，商品加购物车、商品支付、商品发货等一系列流程，包括pc端和手机H5端。</p> </div> <a href="/xiazai/code/11227" title="商城购物系统" class="aritcle_card_btn flexRow flexcenter"><b></b><span>下载</span> </a> </div> </div>

<?php

$sql = "select * from juese";

$arr = $db->query($sql,1);

foreach($arr as $v)

{

echo "<input type="'checkbox'" class="'ck'" value="'{$v[0]}'/">{$v[1]}";

}

?>

3.为了修改权限加一个确认保存按钮

<input type="</code"><code class="php string" style="margin:0px!important; padding:0px!important; background:none!important; border:0px!important; bottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.8em!important; outline:0px!important; overflow:visible!important; position:static!important; right:auto!important; top:auto!important; vertical-align:baseline!important; width:auto!important; font-family:Consolas," bitstream vera sans mono new min-height:auto color:blue>"button" value="保存" id="baocun" />

4.这样，再考虑怎么让数据库中用户本有的角色显示出来，那就是要用到下拉列表和复选框的值了

可以把它写入方法里，然后调用这个方法

function Xuan()

{

var uid = $("#user").val();

$.ajax({

url:"chuli.php",

data:{uid:uid},

type:"POST",

dataType:"TEXT",

success: function(data){

var js = data.trim().split("|");

var ck = $(".ck");

ck.prop("checked",false);

for(var i=0;i<ck.length></ck.length>

{

var v = ck.eq(i).val();

if(js.indexOf(v)>=0)

{

ck.eq(i).prop("checked",true);

}

})

}

5.各项值的处理页面

<?php

require"../DBDA.class.php";

$db = new DBDA();

$uid = $_POST["uid"];

$sql = "select jueseid from userinjuese where userid='{$uid}'";

echo $db->strquery($sql);

效果如下：

6.最后就是保存修改后的值了，可以直接用全部删除在重新写入的方法来进行值的选择；对保存按钮添加单击事件

Xuan();

$("#user").change(function(){

Xuan();

})

$("#baocun").click(function(){

var uid = $("#user").val();

var str = "";

var ck = $(".ck");

for(var i=0;i<ck.length></ck.length>

{

if(ck.eq(i).prop("checked"))

{

str = str + ck.eq(i).val()+",";

}

str = str.substr(0,str.length-1);

$.ajax({

url:"add.php",

data:{uid:uid,js:str},

type:"POST",

dataType:"TEXT",

success: function(data){

alert("保存成功！");

}

})

7.保存的处理页面

<?php

require "../DBDA.class.php";

$db = new DBDA();

$uid = $_POST["uid"];

$js = $_POST["js"];

//清空原有角色

$sql = "delete from userinjuese where userid='{$uid}'";

$db->query($sql);

//添加选中的角色

$ajs = explode(",",$js);

foreach($ajs as $v)

{

$sql = "insert into userinjuese values('','{$uid}','{$v}')";

$db->query($sql);

}

效果如下：

下面代码用来copy用，注意AJAX需要引用Jquery

1.guanli.php

/code><code class="php plain" style="margin:0px!important; padding:0px!important; background:none!important; border:0px!important; bottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.8em!important; outline:0px!important; overflow:visible!important; position:static!important; right:auto!important; top:auto!important; vertical-align:baseline!important; width:auto!important; font-family:Consolas," bitstream vera sans mono new min-height:auto>>

<code class="php plain" style="margin:0px!important; padding:0px!important; background:none!important; border:0px!important; bottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.8em!important; outline:0px!important; overflow:visible!important; position:static!important; right:auto!important; top:auto!important; vertical-align:baseline!important; width:auto!important; font-family:Consolas," bitstream vera sans mono new min-height:auto>>
