userbased content from session php - php

Question

I'm looking to setup a group field for my custom user script. How can I go about only showing certain content to certain groups
Example:
admin (all content)
moderator (extended content)
user (user content)
guest (general overview)
4 group id's 0 - 4
4 banned
3 admin
2 moderator
1 user
0 guest
Example of the PHP in use
// Keep reminding the user this account is not active, until they activate
if($row['group_id'] == 4) { //display all
echo
'<div class="info">
This account is at risk of being banned Please obey the site rules.
</div>';
} else {
exit();
}
Example of the PHP MySQL session
/* Displays user information and some useful messages */
session_start();
// Check if user is logged in using the session variable
if ( $_SESSION['logged_in'] != 1 ) {
$_SESSION['message'] = "You must log in before viewing your profile page!";
header("location: http://localhost/login-system/error.php");
}
else {
// Makes it easier to read
$first_name = $_SESSION['first_name'];
$last_name = $_SESSION['last_name'];
$email = $_SESSION['email'];
$active = $_SESSION['active'];
$group_id = $_SESSION['group_id'];
}

You can do this with this example:
Lets say in this is a blog.
<?php
// 0 = Banned
// 1 = User
// 2 = Admin
if($_SESSION['group_id'] == 0) {
?>
<h1>You Are Banned</h1>
<?php
} elseif($_SESSION['group_id'] == 1) {
?>
<p>Welcome to my blog.</p>
<?php
} elseif($_SESSION['group_id'] == 2) {
?>
<p>Welcome to my blog.</p><button>Delete Post</button>
<?php
}
Or you can do this by a second method:
<p id="1">Welcome To My Blog!</p><button id="2">Delete Content</button>
<h1 id="3">You are banned from this website!</h1>
<?php
if($_SESSION['group_id'] == 0) {
echo '<style>
#2 {
display:none;
}
#3 {
display:none;
}
</style>';
} elseif ($_SESSION['group_id'] == 1) {
echo '<style>
#1 {
display:none;
}
#3 {
display:none;</style>';
} elseif ($_SESSION['group_id'] == 2) {
echo '<style>
#1 {
display:none;
}';
}
Hope this helps!
