PHP实现模拟双色球选号和开奖

平时偶尔也会买买彩票玩，但是感觉真的很少很少概率才会中奖，于是今天突发奇想，自己写个在线模拟双色球开奖和选号的程序，模拟一下中奖几率，以及过过干瘾，哈哈。

废话不多说，直接上代码

<?php

class DoubleColorBall {
    
    private $maxWinningAmount = 0; // 记录中奖最大金额
    private $maxWinningNumber; // 记录中奖最大号码
    
    // 生成指定数量的随机号码
    public function generateRandomNumbers($count) {
        $numbers = [];
        
        for ($i = 0; $i < $count; $i++) {
            $redBalls = [];
            
            // 随机生成6个不重复的红球号码（1-33）
            while (count($redBalls) < 6) {
                $ball = mt_rand(1, 33);
                
                if (!in_array($ball, $redBalls)) {
                    $redBalls[] = $ball;
                }
            }
            
            sort($redBalls); // 对红球号码进行排序
            
            $blueBall = mt_rand(1, 16); // 随机生成一个蓝球号码（1-16）
            
            $numbers[] = array(
                'redBalls' => $redBalls,
                'blueBall' => $blueBall
            );
        }
        
        return $numbers;
    }
    
    // 计算购买成本
    public function calculateCost($numbers, $pricePerTicket) {
        $count = count($numbers);
        $cost = $count * $pricePerTicket;
        
        return $cost;
    }
    
    // 检查指定号码是否中奖，并返回中奖金额
    public function checkWinning($selectedNumber, $winningNumber) {
        $selectedRedBalls = $selectedNumber['redBalls'];
        $selectedBlueBall = $selectedNumber['blueBall'];
        
        $winningRedBalls = $winningNumber['redBalls'];
        $winningBlueBall = $winningNumber['blueBall'];
        
        $matchedRedBalls = array_intersect($selectedRedBalls, $winningRedBalls);
        $matchedRedCount = count($matchedRedBalls);
        
        $matchedBlueBall = ($selectedBlueBall == $winningBlueBall);
        
        if ($matchedRedCount == 6 && $matchedBlueBall) {
            return 10000000;
        } elseif ($matchedRedCount == 6) {
            return 500000;
        } elseif ($matchedRedCount == 5 && $matchedBlueBall) {
            return 3000;
        } elseif ($matchedRedCount == 5 || ($matchedRedCount == 4 && $matchedBlueBall)) {
            return 200;
        } elseif ($matchedRedCount == 4 || ($matchedRedCount == 3 && $matchedBlueBall)) {
            return 10;
        } elseif ($matchedBlueBall) {
            return 5;
        } else {
            return 0;
        }
    }
    
    // 计算中奖金额
    public function calculateWinnings($numbers, $winningNumber) {
        $totalWinnings = 0;
        
        foreach ($numbers as $number) {
            $winnings = $this->checkWinning($number, $winningNumber);
            
            if ($winnings > $this->maxWinningAmount) {
                $this->maxWinningAmount = $winnings;
                $this->maxWinningNumber = $number;
            }
            
            $totalWinnings += $winnings;
        }
        
        return $totalWinnings;
    }
    
    // 获取中奖最大号码
    public function getMaxWinningNumber() {
        return $this->maxWinningNumber;
    }
    
    // 获取中奖最大金额
    public function getMaxWinningAmount() {
        return $this->maxWinningAmount;
    }
    
      // 生成开奖号码
    public function generateWinningNumber() {
        $redBalls = [];
        
        // 随机生成6个不重复的红球号码（1-33）
        while (count($redBalls) < 6) {
            $ball = mt_rand(1, 33);
            
            if (!in_array($ball, $redBalls)) {
                $redBalls[] = $ball;
            }
        }
        
        sort($redBalls); // 对红球号码进行排序
        
        $blueBall = mt_rand(1, 16); // 随机生成一个蓝球号码（1-16）
        
        return array(
            'redBalls' => $redBalls,
            'blueBall' => $blueBall
        );
    }
    
}

// 示例用法
$lottery = new DoubleColorBall();

$numberOfTickets = 100000; // 指定购买的号码数量
$pricePerTicket = 2; // 每张彩票的价格

$selectedNumbers = $lottery->generateRandomNumbers($numberOfTickets);
$winningNumber = $lottery->generateWinningNumber();

$totalCost = $lottery->calculateCost($selectedNumbers, $pricePerTicket);
$totalWinnings = $lottery->calculateWinnings($selectedNumbers, $winningNumber);
$profit = $totalWinnings - $totalCost;

$maxWinningNumber = $lottery->getMaxWinningNumber();
$maxWinningAmount = $lottery->getMaxWinningAmount();

echo "开奖号码是：" . json_encode($winningNumber) . "\n";
echo "您购买了" . $numberOfTickets . "张彩票，总成本为：" . $totalCost . "元\n";
echo "中奖金额为：" . $totalWinnings . "元\n";
echo "利润为：" . $profit . "元\n";

echo "中奖最大的一注号码是：" . implode(",", $maxWinningNumber['redBalls']) . "，蓝球号码是：" . $maxWinningNumber['blueBall'] . "\n";

这里我模拟购买了10万张彩票（真买的话要20万元，哈哈哈）,下面是运行结果:
