我有多個JavaScript函數來計算瑪雅星座符號，我將其轉換爲單個PHP類。一切運作良好，除了某些日期。例如，日期06.10.1977使用PHP類給了我一個NULL結果，但是這個日期在等效的JavaScript函數中返回一個合適的值。也許我在PHP中遇到了問題，那麼有人可以檢查我嗎？將Javascript函數轉換爲PHP類

是不是有點晚了，開始使用瑪雅曆法？在你啓動並運行的時候，如果我沒有弄錯，我們會很快離開 –
你的JavaScript中的'amod'函數在哪裏？在那裏的東西似乎做了一些你在PHP中做的簡單模數。這是腳本失敗的地方，返回0作爲第一個數組值，這對於進一步處理似乎是無效的。 – MiDo
