php 计算 八字 神煞

计算八字神煞需要通过八字计算工具和八字神煞表来完成。以下是一个简单的 PHP 代码示例，用于计算八字神煞：

<?php
// 八字计算函数
function bazi($year, $month, $day, $hour)
{
    // 计算公式
    // 具体可以参考：https://baike.baidu.com/item/%E5%85%AB%E5%AD%97/1093087
    $bz = array("甲","乙","丙","丁","戊","己","庚","辛","壬","癸");
    $sz = array("子","丑","寅","卯","辰","巳","午","未","申","酉","戌","亥");
    $lunar = new Lunar();
    $data = $lunar->convertSolarToLunar($year, $month, $day);
    $nlMonth = $data[4] < 10 ? "0".$data[4] : $data[4];
    $nlDay = $data[5] < 10 ? "0".$data[5] : $data[5];
    $hourIndex = intval(($hour+1)/2);
    $bzYear = $bz[($year-4)%10];
    $bzMonth = $bz[(($year-4)%60)%12];
    $bzDay = $bz[(($year-4)*5+$data[4]+9)%60%12];
    $bzHour = $bz[($hourIndex-1)%10];
    $szYear = $sz[($year-4)%12];
    $szMonth = $sz[$data[4]-1];
    $szDay = $sz[$data[5]-1];
    $szHour = $sz[$hourIndex%12];
    $result = array(
        "year" => $bzYear . $szYear,
        "month" => $bzMonth . $szMonth,
        "day" => $bzDay . $szDay,
        "hour" => $bzHour . $szHour
    );
    return $result;
}

// 八字神煞计算函数
function shensha($bazi)
{
    // 具体可以参考：https://www.jiankang.com/suanming/bazi/sssm.htm
    $ss = array(
        "天乙贵人" => ["甲", "乙", "戊", "己"],
        "太极贵人" => ["甲", "乙", "丙", "丁", "戊", "己", "庚", "辛"],
        "文昌贵人" => ["甲", "丙", "戊", "庚", "壬"],
        "文曲星" => ["乙", "丙", "戊", "庚", "壬"],
        "左辅" => ["乙", "丁", "己", "辛"],
        "右弼" => ["甲", "戊", "庚", "壬"],
        "天喜" => ["丙", "戊", "庚", "壬"],
        "月德贵人" => ["寅", "午", "戌"],
        "月破" => ["申", "子"],
        "月厌" => ["丑", "未"],
        "月刑" => ["辰", "戌", "丑", "未"],
        "日禄" => ["甲", "己"],
        "日贵" => ["乙", "庚"],
        "日空" => ["戊", "丁"],
        "日刑" => ["癸", "辛", "壬", "丙"]
    );
    $result = array();
    foreach ($ss as $key => $value) {
        $bz = substr($bazi[$key], 0, 3);
        if (in_array($bz, $value)) {
            array_push($result, $key);
        }
    }
    return $result;
}

// 测试代码
$bazi = bazi(1990, 12, 24, 18);
$shensha = shensha($bazi);
echo "八字：".$bazi["year"]."年 ".$bazi["month"]."月 ".$bazi["day"]."日 ".$bazi["hour"]."时\n";
echo "八字神煞：".implode(", ", $shensha);
?>

需要注意的是，此代码中使用了一个 `Lunar` 类来进行公历和农历之间的转换，需要自行实现或引用此类。除此之外，还需要一个八字神煞表来进行匹配。
