PHP development enterprise website tutorial - exit

After successful login, we enter the main.php page and enter the management page

Let’s take a look at the following top.php page

<?php
    session_start();
?>
<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta charset="utf-8">
    <style type="text/css">
            body{margin-top:50px;text-align:center;}
            a{text-decoration:none;float:right;margin-right:15px;color:red;}
    </style>
</head>
<body>
    <h1>合肥领航环保科技公司后台管理系统</h1>
    <?php
        if(!empty($_SESSION['username'])){
    ?>
    <a href="loginout.php?act=loginout" target="_top">退出</a>
    <?php
        }
    ?>
    
</body>
</html>

We also need to open the session first. After successful login before, we The form information has been stored in the session. Now we will judge the username in the session on this page. If the username in the session has a value

we will display the exit on the top page

Let’s look at the following exit Function code

Exit and submit to loginout.php

Let’s look at the code:

<?php
session_start();
if($ _GET['act'] == 'loginout'){
unset($_SESSION);
echo "<script>location.href='log.php';</script>";
}

?>

In this way we have completed the exit function
