php权限管理

2018-06-22 05:16:25来源：未知阅读 ()

首先权限管理肯定是需要登陆的，这里就简单的写一个登陆页面。

简单的登陆页面login.php

<h1>登录页面</h1>
<form action="logincl.php" method="post">
<input type="text" name="uid" />
<input type="password" name="pwd" />
<input type="submit" value="登录" />
</form>

登陆处理页面logincl.php

<?php
session_start();
include("../FENGZHUANG/DBDA.class.php");
$db = new DBDA();
$uid = $_POST["uid"];
$pwd = $_POST["pwd"];

$sql="select pwd from users where uid='{$uid}'";
$mm = $db->StrQuery($sql); 

if($mm==$pwd && !empty($pwd))
{
    $_SESSION["uid"]=$uid;
    header("location:main.php");
}

登陆完成后进入主页面main.php

<h1>主页面</h1>
<?php
session_start();
include("../FENGZHUANG/DBDA.class.php");
$db = new DBDA();

if(empty($_SESSION["uid"]))
{
    header("location:login.php");
    exit;
}
//登录者用户名
$uid = $_SESSION["uid"];

//根据用户名查角色
$sjs = "select jueseid from userinjuese where userid='{$uid}'";
$ajs = $db->Query($sjs);
//定义一个存放功能代号的数组
$arr = array();
//根据角色代号查功能代号
foreach($ajs as $vjs)
{
        $jsid = $vjs[0]; //角色代号
        $sgn = "select ruleid from juesewithrules where jueseid='{$jsid}'";
        $strgn = $db->StrQuery($sgn);
        $agn = explode("|",$strgn);
        
        foreach($agn as $vgn)
        {
            array_push($arr,$vgn);
        }    
}

//去重，显示
$arr = array_unique($arr);
foreach($arr as $v)
{
    $sql = "select * from rules where code='{$v}'";
    $attr = $db->Query($sql);
    
    $attr[0][0]; $attr[0][1];
    
    echo "<div code='{$attr[0][0]}'>{$attr[0][1]}</div>";
}

?>

</body>
