Help me please?

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

//change to switch statement if ($role != 'admin') { echo "You do not have access to this page. Please contact your administrator."; } switch ($message) { case 1: $message = "Hello"; } echo $message;

cant understand about case

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

//change to switch statement
if ($role != 'admin') {
    echo "You do not have access to this page. Please contact your administrator.";
} switch ($message) {
  case 1: 
  $message = "Hello";
}
echo $message;

Hi Ivan, this is the code that passes the challenge:

<?php
switch ($role) { 
/* inside brackets is the condition - in this case it is $role - 
we are going to compare values against this condition*/
    case 'admin': // here we check whether $role == 'admin' if so we echo following sentence
      echo 'As an admin, you can add, edit, or delete any post.';
      break;

    default: // this is default case - so if $role != 'admin' - following sentence will be printed out
      echo 'You do not have access to this page. Please contact your administrator.';
      break;
}
?>

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

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

default:
  echo 'You do not have access to this page. Please contact your administrator.';
  break;

} ?>

incorrect output

Just, delete opening and closing php tags around the switch statement - I included them so it would highlight php syntax. Also after comment "//change to switch statement " delete original if statement and leave just switch statement.

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

//change to switch statement
switch ($role) { 
/* inside brackets is the condition - in this case it is $role - 
we are going to compare values against this condition*/
    case 'admin': // here we check whether $role == 'admin' if so we echo following sentence
      echo 'As an admin, you can add, edit, or delete any post.';
      break;

    default: // this is default case - so if $role != 'admin' - following sentence will be printed out
      echo 'You do not have access to this page. Please contact your administrator.';
      break;
}
