  Use an expression to select an array value in PHP. It's handy for quick output logic. Update: it's a bit too clever, perhaps, versus using the tenary operator.

  $classes .= [ ' sort-default', ' sort-custom' ][ has_custom_sort( $post ) ];

• Basic routing using REQUEST_URI

  Sander @ March 21, 2023 at 12:41 pm

  So for nginx it is not straightforward to setup PHP-FPM so that PATH_INFO is correctly populated. Lamb uses the following /index.php/some/other type routing, where /some/other should be the PATH_INFO. Instead I want to make setup for a variety of web-servers straightforward, so I've switched to the more robust REQUEST_URI. This simplifies nginx configuration and Caddy and the PHP built-in web-server are compatible.

  REQUEST_URI contains everything after the domain name, including the query string, so that needs to be removed:

  $request_uri = '/home';
  if ( $_SERVER['REQUEST_URI'] !== '/' ) {
      $request_uri = strtok( $_SERVER['REQUEST_URI'], '?' );
  }

  We can see that for a request for the root of the site, REQUEST_URI returns / whereas PATH_INFO would be empty, so the code above takes that into account. We can then deduct a router action as follows:

  $action = strtok( $request_uri, '/' );

  Once the $action is known, it can be checked against an allowed list of actions:

  switch ( $action ) {
      case 'edit':
          ...
          break;
      default:
          respond_404();
          break;
