1.2.649. Long Preparation For Throw

When throwing an exception, move the preparing code in the exception. This will keep the throw call simple.

<?php

// Examples extracted from Alain Schlesser's blog
public function render( $view ): string {

   if ( ! $this->views->has( $view ) ) {
      switch ( gettype( $view ) ) {
         case 'object':
            $view = get_class( $view );
         case 'string':
            $message = sprintf(
               'The requested View "%s" does not exist.',
               $view
            );
            break;
         default:
            $message = sprintf(
               'An unknown View type of "%s" was requested.',
               $view
            );
      }

      throw new ViewWasNotFound( $message );
   }

   echo $this->views->get( $view )
             ->render();
}

?>
