PHP PHP Arrays and Control Structures PHP Conditionals Operators

Is my code valid? It passes, and I've seen different ways to do this, I just want to know if my code is right.

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

//add conditional statement //Should I have used the OR || operator instead of the && operator or does that matter? if ($username = true && $role != 'admin'){ echo "You do not have access to this page. Please contact your administratior."; } ?>

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

//add conditional statement
echo "You do not have access to this page. Please contact your administratior.";

Hi there Key!

Even if this solution passes, your condition is not correct. Because you are assigning to the variable $username boolean value. Which in condition statement will evaluate to true. Second condition will also evaluate to true because role is not admin.

if ($username = true && $role != 'admin')

In order to check if string is not empty, simply remove assigning operator.

if ($username && $role != 'admin')

But in your case, you need to check if variable exist. OR operator is not an option here because you need to check both conditions at same time.

if (isset($username) && $role != 'admin')

Here is some useful docs for you. http://php.net/manual/en/function.isset.php

Best regards.

Thank you for responding to my post! I had a gut feeling that it wasn't correct even though it passed.
