PHP PHP Arrays and Control Structures PHP Conditionals Operators

Can't find my mistake in Code Challange Operators.

Hey there, I'm getting crazy - I just can't see why the system tells me to "Use the negation operator to check that $role is NOT EQUAL to "admin"" - I thought I did!

In the Preview everything works fine....

Thank you for your help!

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 administrator.";}
?>

I think that your program functions as intended. Since your username is set and your role is assigned a string of "editor", your program outputs: "You do not have access to this page. Please contact your administrator.", just as it should. Is this not intended behavior?

Thanks for your reply Mihkel Pajunen. Yes that's the intended behavior. And it works in the Console. But the Code-Challange-System doesn't let me go on with this solution. So I began to doubt ... you know I'm a noob in PHP ;)

OK now I finally got It. There where only some blanks missing. Before and after != I don't think they're necessary outside this challange, are they?

You don't have to include a space before and after the operator, but it makes your code more readable, which is always a good thing. Although your code executes either way, you want to pick up good coding practices, such as applying proper spacing.
