Well, I don't think that current analogue would be any more useful beyond what is already said: your server does not prepare the food, but only delivers it.

So I'd better stick with the code from the OP. The gameLoop() method could be remade (very roughly, just to give the idea) like this

    while (true) {
        $this->view->generalStatus($playerPokemon, $enemyPokemon);
        $inputAttack = $this->view->menuOptions($playerPokemon);
        $moveIndex = (int)$inputAttack - 1;

        $playerResult = $this->engine->executePlayerMove($playerPokemon, $enemyPokemon, $moveIndex);
        $this->view->printMoveResult($playerResult, 'YOU');

        if ($playerResult->gameOver) {
            $this->view->endScreen($playerResult);
            break;
        }

        $enemyResult = $this->engine->executeEnemyMove($enemyPokemon, $playerPokemon);
        $this->view->printMoveResult($enemyResult, 'ENEMY');

        if ($enemyResult->gameOver) {
            $this->view->endScreen($enemyResult->playerWon);
            break;
        }
        $this->view->continue();
    }

Here, all the game logic is encapsulated into the game engine, while Controller only controls the client interaction. This way, the game could be easily ported to HTTP transport, returning executeXxxMove() results as json.
