How could I switch from an array?-CodePudding

I'm trying to route set of array, but it's not working.

<?php
$routes = array('home'=>'Home Page','about'=>'About Me');
$action = isset($_GET['action']) ? $_GET['action'] : '';
switch($action) {
  foreach($routes as $key => $value) {
    case $key:
      echo $value;
      break;
  }
}

But instead, it returns Parse error: syntax error, unexpected token "foreach", expecting "case" or "default" or "}"

I don't think you can do that, even if you could, I would advise against it as it is not a conventional practice.

Why not just use something like the following?

<?php
$routes = array('home'=>'Home Page','about'=>'About Me');
$action = isset($_GET['action']) ? $_GET['action'] : '';
if (array_key_exists($action, $routes)) {
  echo $routes[$action];
} else {
  // Do you error handling here.
}

Try to solve it this way, with using filter_input on get variable:

<?php
$routes = array('home'=>'Home Page','about'=>'About Me');
$action = filter_input(INPUT_GET, 'action');
if ($action) {
  echo $routes[$action];
}
