What are some common pitfalls to avoid when adding new levels to a game in PHP?

One common pitfall to avoid when adding new levels to a game in PHP is not properly organizing your code structure. It's important to separate your game logic from your level data to make it easier to add and modify levels in the future. Additionally, make sure to thoroughly test each new level to ensure it works as intended before releasing it to players.

// Example of organizing code structure for adding new levels
class Game {
    private $levels = [];

    public function __construct() {
        $this->loadLevels();
    }

    private function loadLevels() {
        // Load level data from external source (e.g. database, JSON file)
        $levelsData = [
            // Level data here
        ];

        foreach ($levelsData as $levelData) {
            $this->levels[] = new Level($levelData);
        }
    }
}

class Level {
    private $data;

    public function __construct($data) {
        $this->data = $data;
    }

    public function getData() {
        return $this->data;
    }
}
