isset and operator functions

Hi everyone, the challenge task following the logical operators video requires an "isset" function to be used, but it was not mentioned in the video or the teachers notes as I saw. I was only able to answer it based on the information in the community posts. Am I missing something or was there information missing?

index.php 
<?php
$username = 'sketchings';
//Available roles: author, editor, admin
$role = 'editor';

//add conditional statement
  if  (isset)($username) && $role != 'admin') {
  echo "You do not have access to this page. Please contact your administratior.";
  }

You can actually get this to work a couple different ways:

<?php
if($username != '' && $role != "admin") {
echo "You do not have access to this page. Please contact your administratior.";
}

Or even

<?php
if(!empty($username) && $role != "admin") {
echo "You do not have access to this page. Please contact your administratior.";
}

The first is pretty simple, just saying username isn't an empty string (or, plainly, two single quotes with nothing between), the second uses a function I'm sure she has used before (although, not sure if it's been used in this track).
