You have saved the fullName as $_SESSION["user"]["fullname"] :
```
$_SESSION["user"]["fullname"] = $user["fullname"];
```
But you are echoing this way:
```
echo $_SESSION["fullname"];
```
Fix it to echo the correct one:
```
echo $_SESSION["user"]["fullname"];
```
Note: You can use additional check if(isset($_SESSION["user"]["fullname"])) so that you don't get error, when it is not actually set. But that will fix nothing until you use the correct variable / key.

The session_start() function must be the very first thing in your document. Before any HTML tags. Try this:
```
<?php
  session_start();
?>
<!DOCTYPE html>
<html>
<body>
```

You have space before declaring session variable.
```
  <?php
session_start();
?>
```
Note the space before <?php. This will create an issue so just remove it.
