php Determine whether the user is logged in
The following example uses Session to determine whether the user is logged in:

<?php
function loggedIn(){
//通过 $_SESSION 来判断用户是否登录
if(!$_SESSION['loggd']){
echo'<form action="checkLogin.php" method="post">
<p>
Username:<br>
<input type="text" name="username">
</p>
<p>
Password:<br>
<input type="password" name="username">
</p>
<p>
<input type="submit" name="submit" value="Log In">
</p>
</form>';
}else{ // 登录显示欢迎页面
echo 'Welcome, '.$_SESSION['username'];
}
}
?>index.php
<?php
//Start the session
session_start();
//This is a simplified HTML Document
?>
<html>
<head>
<title>My Page</title>
