php personnel authority management (RBAC)
Before talking about permission management, you should first know what functions permission management has:
(1) Users can only access, specify Controller, specified method
(2) Users can exist in multiple user groups
(3) User groups You can choose the specified controller and the specified method
(4), you can add the controller and method
RBAC (Role-Based Access Control (role-based access control) is where users are associated with permissions through roles. Simply put, a user has several roles, and each role has several permissions. In this way, a "user-role-permission" authorization model is constructed. In this model, there is generally a many-to-many relationship between users and roles, and between roles and permissions.
1. Database design
Write five tables, first: user table, role table, function table:
Connection Table of tables.. Next is the role function table and user role table:
2. Administrator's Management page,
<?php
include ("../db.class.php");
$db = new db();
$sql = "select * from qxyh";
$arr = $db->Query($sql);
foreach ($arr as $v)
{
echo "<option value='{$v[0]}'>{$v[2]}</option>";
}
?>(1). Display user name and role name respectively
(2). According to the drop-down user name Change, change the role in the corresponding check box
(3). When modifying the user role, first delete the user's corresponding role table and all the information of this user, and then retrieve The username and role code are newly added.
Use the drop-down list: embed the php query and traverse it, display it in the form of a drop-down list
Select the role, use multiple Marquee:
<p style="margin-bottom: 7px;"><p>请选择角色<br/><?php<br/>$sjs = "select * from qxzw";<br/>$ajs = $db->Query($sjs);<br/>foreach ($ajs as $v){ <br/> echo "<input type='checkbox' value='{$v[0]}' class='ck'/>{$v[1]} ";<br/>}?><br/></p><br/><input type="button" value="确定" id="btn"/><br/></p>Picture:
##When the user changes, the corresponding role also changes accordingly, and the person's role information is changed and added and saved. The basic idea of adding and saving is to first delete all the role information corresponding to the person in the database, and then retrieve it. The selected part is added to the database.
Let him select the default role first:
<script>
//选中默认角色
function xuan()
{
var uid = $("#user").val();
$.ajax({
url:"chuli.php",
data:{uid:uid,type:0},
type:"POST",
dataType:"TEXT",
success:function(data)
{
var juese = data.trim().split("|");
//拆分完全都变成代号
var ck = $(".ck");
ck.prop("checked",false);
for(var i=0;i<ck.length;i++)
{
//便利所有的列表
if(juese.indexOf(ck.eq(i).val())>=0)
{
ck.eq(i).prop("checked",true);
}
}
}
});
}
</script>To write his processing page:
<?php
include ("../db.class.php");
$db = new db();
$type = $_POST["type"];
switch ($type)
{
case 0:
$uid = $_POST["uid"];
$sql = "select jid from qxyhzw WHERE uid='{$uid}'";
echo $db->strQuery($sql);
break;
}Let’s take a look at the final result. If you log in successfully, you will enter the homepage. If you log in failed, you will get an error
## Come again, save button: <script>//当用户变化的时候去选中相应角色
$("#user").change(function(){
xuan();
}) //点击确定保存角色信息
$("#btn").click(function(){ var uid = $("#user").val(); //找到用户名
var juese = "";// 找到角色代号
var ck = $(".ck"); //找到所有的checked
for(var i=0;i<ck.length;i++)
{// 遍历他
if(ck.eq(i).prop("checked"))
{// 如果他选中了，两个参数是改他的状态
//娶过来值；加个|分割一下
juese += ck.eq(i).val()+"|";
}
}
juese = juese.substr(0,juese.length-1);// 去掉最后的| $.ajax({
url:"chuli.php",
data:{uid:uid,juese:juese,type:1},
type:"POST",
dataType:"TEXT",
success:function(data){
alert("修改成功");
}
});
})
});</script>
Processing page:<?php
include ("../db.class.php");
$db = new db();
$type = $_POST["type"];
switch ($type)
{
case 1:
$uid = $_POST["uid"];
$juese = $_POST["juese"];
// 首先全部删掉里面的职位
$sdel = "delete from qxyhzw WHERE uid = '{$uid}'";
$db->Query($sdel,0);
//拆分取到的字符串
$arr= explode("|",$juese);
foreach ($arr as $v)
{
$sql = "insert into qxyhzw VALUES ('','{$uid}','{$v}')";
$db->query($sql,0);
}
echo "ok";
break;
}
See the effect:
The role is selected by default;
Choose to save after making changes:
用户与角色管理
<?php
include ("../db.class.php");
$db = new db();
$type = $_POST["type"];
switch ($type)
{
case 0:
$uid = $_POST["zhang"];
$sql = "select jid from qxyhzw WHERE uid='{$uid}'";
echo $db->strQuery($sql);
break;
case 1:
$uid = $_POST["zhang"];
$juese = $_POST["juese"];
// 首先全部删掉里面的职位
$sdel = "delete from qxyhzw WHERE uid = '{$uid}'";
$db->Query($sdel,0);
//拆分取到的字符串
$arr= explode("|",$juese);
foreach ($arr as $v)
{
$sql = "insert into qxyhzw VALUES ('','{$uid}','{$v}')";
$db->query($sql,0);
}
echo "ok";
break;
}
The display is very simple:
<form action="drcl.php" method="post">
<p>帐号:<input type="text" name="zhang"/></p>
<p>密码:<input type="text" name="mi"/></p>
<input type="submit" value="登入"/></form>Write login processing
<?php
session_start();
include ("../db.class.php");
$db = new db();
$zhang = $_POST["zhang"];
$mi = $_POST["mi"];
$sql = "select mi from qxyh WHERE zhang = '{$zhang}'";$mm = $db->strQuery($sql)>0;
if($mm = $mi && !empty($mi)){
$_SESSION["zhang"] = $zhang;
header("location:chaxun.php");
}//else
//{
// echo "登入失败";
//}
Everyone’s main page is different of

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
