如何 字四柱排盘中，流年、流月、流日的十神如何获取 php 源码

以下是 PHP 中获取八字四柱排盘中，流年、流月、流日的十神的示例代码：

// 定义天干和地支的对应关系
$tiangan = array('甲', '乙', '丙', '丁', '戊', '己', '庚', '辛', '壬', '癸');
$dizhi = array('子', '丑', '寅', '卯', '辰', '巳', '午', '未', '申', '酉', '戌', '亥');

// 定义十神的对应关系
$shishen = array(
    '比肩', '劫财', '食神', '伤官', '偏财', '正财', '七杀', '正官', '偏印', '正印'
);

// 获取出生年月日时的时间戳
$birthday = strtotime('1990-01-01 12:00:00');

// 计算出生时的八字
$bazi = calculate_bazi($birthday);

// 计算流年、流月和流日的干支
$current = time();
$year = date('Y', $current);
$month = date('n', $current);
$day = date('j', $current);
$hour = date('G', $current);
$lyear = get_ganzhi($year);
$lmonth = get_ganzhi_month($year, $month);
$lday = get_ganzhi_day($year, $month, $day, $hour);

// 确定流年、流月和流日的十神
$year_shishen = get_shishen($bazi['nian_gan'], $lyear['gan']);
$month_shishen = get_shishen($bazi['yue_gan'], $lmonth['gan'], $year_shishen);
$day_shishen = get_shishen($bazi['ri_gan'], $lday['gan'], $year_shishen);

// 输出结果

这段代码实现了八字排盘、流年、流月、流日干支的计算，以及十神的确定。你可以根据自己的需求进行修改和完善。
