我有多个 JavaScript 函数来计算玛雅星座，我将其转换为单个 PHP 类。一切都很好，除了一些日期。例如，日期06.10.1977使用 PHP 类给我一个 NULL 结果，但等效 JavaScript 函数中的这个日期返回一个正确的值。也许我在 PHP 中出了点问题，有人可以帮我检查一下吗？

第一：总是发布所有相关的脚本。您缺少对解决您的问题至关重要的 JavaScript 函数 amod()，我在原始版本中找到了它

您的 PHP 函数jd_to_mayan_tzolkin()与您的 JavaScript 函数不同jd_to_mayan_tzolkin()：

而 JavaScript 使用单独的函数amod()来计算模数并在模数结果为时返回分子0

//  AMOD  --  Modulus function which returns numerator if modulus is zero
function amod($a, $b) {
  return $this->mod($a - 1, $b) + 1;
}

您的 php 函数只返回可能的模数，0因此您的 PHP 的进一步处理失败。

将以下两个函数添加到您的类中：

/*  MOD  --  Modulus function which works for non-integers.  */
private function mod($a, $b) {
  return $a - ($b * floor($a / $b));
}

//  AMOD  --  Modulus function which returns numerator if modulus is zero
private function amod($a, $b) {
  return $this->mod($a - 1, $b) + 1;
}

并更改PHP方法jd_to_mayan_tzolkin()如下：

private function jd_to_mayan_tzolkin($jd) {
     $jd = floor($jd) + 0.5;
     $lcount = $jd - $this->MAYAN_COUNT_EPOCH;
     return array($this->amod(($lcount + 20),20), $this->amod(($lcount + 4),13));
}
