What are the potential pitfalls of using Enum data type in PHP for storing win, draw, and loose values in a War module?

Using Enum data type in PHP for storing win, draw, and loose values in a War module can lead to potential pitfalls such as limited portability across different PHP versions and potential performance overhead. To solve this issue, a more flexible and efficient approach would be to use constants or class constants to represent these values.

class WarOutcome {
    const WIN = 'win';
    const DRAW = 'draw';
    const LOSE = 'lose';
}

// Example usage
$player1Outcome = WarOutcome::WIN;
$player2Outcome = WarOutcome::LOSE;
