php权限管理

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>

复制代码

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");
}

复制代码

登陆完成后进入主页面main.php

<body>
<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>
</html>
