How can the issue of waiting for both users to choose an action before deducting damage points be efficiently addressed in PHP scripting?

Issue: To address the problem of waiting for both users to choose an action before deducting damage points in a turn-based game, you can implement a system that tracks the actions chosen by each player and then calculates the damage points once both players have made their choices.

// Example PHP code snippet to address the issue of waiting for both users to choose an action before deducting damage points
class Player {
    public $chosenAction;
    public $damagePoints;

    public function chooseAction($action) {
        $this->chosenAction = $action;
    }

    public function calculateDamagePoints($opponentAction) {
        // Calculate damage points based on the chosen actions of both players
        if ($this->chosenAction == 'attack' && $opponentAction == 'defend') {
            $this->damagePoints = 0; // No damage if opponent defends
        } elseif ($this->chosenAction == 'defend' && $opponentAction == 'attack') {
            $this->damagePoints = 0; // No damage if player defends
        } elseif ($this->chosenAction == 'attack' && $opponentAction == 'attack') {
            $this->damagePoints = 10; // Both players attack, deal 10 damage each
        } else {
            $this->damagePoints = 5; // Default damage points
        }
    }
}

// Usage example
$player1 = new Player();
$player2 = new Player();

$player1->chooseAction('attack');
$player2->chooseAction('defend');

// Wait for both players to choose an action before calculating damage points
if ($player1->chosenAction && $player2->chosenAction) {
    $player1->calculateDamagePoints($player2->chosenAction);
    $player2->calculateDamagePoints($player1->chosenAction);

    echo "Player 1 damage points: " . $player1->damagePoints . "\n";
    echo "Player 2 damage points: " . $player2->damagePoints . "\n";
}
