尝试制作一个简单的网站，用户可以在其中拥有不同的帐户级别。例如，帐户类型为“a”和“b”的用户将在顶部看到一个链接/按钮，上面写着基本，而帐户类型为“c”的用户将看到一个链接/按钮，上面写着完整会员。
我有一个代码几乎可以满足我的需要，它将用户保存在数据库中不同的 A/B/C 类别中。
如上所述，我只需要知道我必须做什么才能显示指向不同帐户类型的不同链接？
另外，我知道下面的代码不是最好的代码，但只需要用我所拥有的来实现我现在所追求的结果。
<?php
session_start(); // Must start session first thing
// See if they are a logged in member by checking Session data
$toplinks = "";
if (isset($_SESSION['id'])) {
// Put stored session variables into local php variable
$userid = $_SESSION['id'];
$username = $_SESSION['username'];
$toplinks = '<a href="member_profile.php?id=' . $userid . '">' . $username . '</a> •
<a href="member_account.php">Account</a> •
<a href="logout.php">Log Out</a>';
} else {
echo 'Please <a href="login.php">log in</a> to access your account';
exit();
}
?>
<?php
//Connect to the database through our include
include_once "scripts/connect_to_mysql.php";
// Query member data from the database and ready it for display
$sql = mysql_query("SELECT * FROM members WHERE id='$userid'");
while($row = mysql_fetch_array($sql)){
$country = $row["country"];
$state = $row["state"];
$city = $row["city"];
$accounttype = $row["accounttype"];
$bio = $row["bio"];
}
// Give different options or display depending on which user type it is
if ($accounttype == "a") {
$userOptions = "You get options for Expert User";
} else if ($accounttype == "b") {
$userOptions = "You get options for Expert User";
} else if ($accounttype == "c") {
$userOptions = "You get options for Expert User";
} else {
$userOptions = "You get options for Super User";
}
?>

请温柔一点，因为我是 PHP 新手，刚刚学习曲线。
谢谢
