PHP 实现彩票遗漏算法

彩票遗漏统计通常指某一号码或组合未出现的期数。以下是基于PHP的实现方法：

数据准备

假设已有历史开奖数据数组，格式如下：

$historyData = [
    ['issue' => '2023001', 'numbers' => [1, 2, 3, 4, 5]],
    ['issue' => '2023002', 'numbers' => [6, 7, 8, 9, 10]],
    // 更多历史数据...
];

单号码遗漏计算

function calculateSingleOmission($historyData, $targetNumber) {
    $omissionCount = 0;
    $latestAppear = '未出现';

    foreach (array_reverse($historyData) as $draw) {
        if (in_array($targetNumber, $draw['numbers'])) {
            $latestAppear = $draw['issue'];
            break;
        }
        $omissionCount++;
    }

    return [
        'number' => $targetNumber,
        'omission' => $omissionCount,
        'last_appear' => $latestAppear
    ];
}

批量计算所有号码遗漏

function batchCalculateOmission($historyData, $numberRange) {
    $results = [];

    foreach ($numberRange as $num) {
        $results[] = calculateSingleOmission($historyData, $num);
    }

    // 按遗漏值排序
    usort($results, function($a, $b) {
        return $b['omission'] - $a['omission'];
    });

    return $results;
}

使用示例

// 定义号码范围（如双色球红球1-33）
$redBallRange = range(1, 33);

// 计算当前遗漏
$currentOmissions = batchCalculateOmission($historyData, $redBallRange);

// 输出结果
print_r($currentOmissions);

数据库优化方案

对于大量历史数据，建议使用数据库查询：

-- 查找号码最后出现期数
SELECT issue FROM lottery_draws 
WHERE FIND_IN_SET(?, numbers) 
ORDER BY issue DESC LIMIT 1;

// 计算当前遗漏期数
$currentIssue = '2023100';
$lastAppear = $db->query($sql, [$targetNumber])->fetchColumn();

$omission = $lastAppear ? 
    (int)$currentIssue - (int)substr($lastAppear, -3) : 
    count($historyData);

遗漏冷热分析扩展

可添加冷热状态判断逻辑：

function getHotStatus($omission, $avgOmission) {
    if ($omission > $avgOmission * 1.5) {
        return '冷号';
    } elseif ($omission < $avgOmission * 0.5) {
        return '热号';
    }
    return '温号';
}
