マヤの星占いの記号を計算するための複数のJavaScript関数があり、それを単一のPHPクラスに変換しました。一部の日付を除いて、すべてがうまく機能します。たとえば、1977年6月10日の日付では、PHPクラスを使用してNULLの結果が得られますが、同等のJavaScript関数のこの日付は適切な値を返します。PHPに何か問題があるので、誰かが私のためにこれをチェックできますか？

最初：関連するすべてのスクリプトを常に投稿してください。あなたの問題を解決するために重要なJavaScript関数amod（）がありませんでした、私はここでオリジナルでそれを見つけました

PHP関数jd_to_mayan_tzolkin()はJavaScript関数と違いはありませんjd_to_mayan_tzolkin()：

JavaScriptは別の関数amod()を使用してモジュラスを計算し、モジュラスの結果が次の場合は分子を返します。0

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

php関数はモジュラスを返すだけな0ので、PHPのそれ以上の処理は失敗します。

次の2つの関数をクラスに追加します。

/*  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;
}

そして、PHPメソッドjd_to_mayan_tzolkin()を次のように変更します。

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));
}
