PHP PHP Arrays and Control Structures PHP Conditionals Switch Statements

Why the question is saying "I do not see the correct default output" when I clearly have it in there.

Try removing the entirety of the case admin part below the default and tell me why it can read the default then but when the case admin is placed back in the question ignores the default despite it still being there,

switch.php 
<?php
//Available roles: admin, editor, author, subscriber
if (!isset($role)) {
    $role = 'subscriber';
}

//change to switch statement
switch ($role != 'admin') {
  default:
    echo "You do not have access to this page. Please contact your administrator.";
      break;
  case 'admin':
      echo 'As an admin, you can add, edit, or delete any post.';
        break;


}

I fixed it, I removed the != 'admin' part and it worked for whatever reason.

You are switching on an expression that evaluates to true or false. As an initial test try the following:

if ('admin' == true) {
    echo 'true';
}

You’ll see that it evaluates to true. You can read about it under Converting to Boolean here

Then before the switch add:

$role = 'admin';

In this case the expression ($role != 'admin') is equivalent to switch(false). Since case 'admin' is true the default is echoed

"You do not have access to this page. Please contact your administrator."

Then change it to 

$role = 'admin2'

For the expression this is equivalent to switch(true) and case 'admin' is echoed

"As an admin, you can add, edit, or delete any post."

If you want to experiment further try adding other cases before case 'admin' or add case false.
