PHP PHP Arrays and Control Structures PHP Conditionals Switch Statements

Switch Case

In the code provided, there are two if statements. The second if statement displays a message IF the user role is not equal to "admin". We want to display separate messages based on the role of the logged in user. First we're going to add a message for our admin and keep the current message as the default.

Step 1: Change the second if statement to a switch statement

Step 2: Keep the current message as the default.

Step 3: Add a second check to the switch statement for the role of "admin" and display the following message:

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

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

//change to switch statement
$role = 'admin';
switch (true) {
  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;
}

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



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.";
}

You didn't need to define $role as thats what the first if statement does and sets it to subscriber. Where you passed the switch statement the word true you want to be passing the piece of code or variable that is going to be checked and finally you don't need to break in the default statement.

Id advise having a look at the w3 schools page for switch statements, thats where I often go to refresh my memory.
