How PHP realizes the Gregorian lunar calendar

This article mainly introduces the method of implementing the Gregorian lunar calendar in PHP, and also can obtain the Ganzhi, Zodiac, and the corresponding lunar calendar Chinese names, etc., interested in small partners can refer to. We hope to help you.

Recently to the Gregorian calendar to get the corresponding holiday algorithm this is more interested in this aspect, so on the internet searched a circle. Good, but also to find a better PHP class, to achieve the conversion of the Gregorian calendar into the lunar calendar (lunar), the lunar calendar conversion to the Gregorian algorithm, but also to obtain the Ganzhi year, the Zodiac, and the corresponding lunar calendar of Chinese names and so on, the function is quite complete, here to share to everyone.
The specific class code is as follows:

Class lunar{var $MIN _year=1891;   var $MAX _year=2100; var $lunarInfo =array (Array (0,2,9,21936), Array (6,1,30,9656), Array (0,2,17,9584), Array (0,2,6,21168), Array ( 5,1,26,43344), Array (0,2,13,59728), Array (0,2,2,27296), Array (3,1,22,44368), Array (0,2,10,43856), Array ( 8,1,30,19304), Array (0,2,19,19168), Array (0,2,8,42352), Array (5,1,29,21096), Array (0,2,16,53856), Array (0,2,4,55632 ), Array (4,1,25,27304), Array (0,2,13,22176), Array (0,2,2,39632), Array (2,1,22,19176), Array (0,2,10,19168), Array ( 6,1,30,42200), Array (0,2,18,42192), Array (0,2,6,53840), Array (5,1,26,54568), Array (0,2,14,46400), Array (0,2,3,54944 ), Array (2,1,23,38608), Array (0,2,11,38320), Array (7,2,1,18872), Array (0,2,20,18800), Array (0,2,8,42160), Array ( 5,1,28,45656), Array (0,2,16,27216), Array (0,2,5,27968), Array (4,1,24,44456), Array (0,2,13,11104), Array (0,2,2,38256 ), Array (2,1,23,18808), Array (0,2,10,18800), Array (6,1,30,25776), Array (0,2,17,54432), Array (0,2,6,59984), Array ( 5,1,26,27976), Array (0,2,14,23248), Array (0,2,4,111), Array (3,1,24,37744), Array (0,2,11,37600), Array (7,1,31,51560), Array (0,2,19,51536), Array (0,2,8,54432), Array ( 6,1,27,55888), Array (0,2,15,46416), Array (0,2,5,22176), Array (4,1,25,43736), Array (0,2,13,9680), Array (0,2,2,37584) , Array (2,1,22,51544), Array (0,2,10,43344), Array (7,1,29,46248), Array (0,2,17,27808), Array (0,2,6,46416), Array ( 5,1,27,21928), Array (0,2,14,19872), Array (0,2,3,42416), Array (3,1,24,21176), Array (0,2,12,21168), Array ( 8,1,31,43344), Array (0,2,18,59728), Array (0,2,8,27296), Array (6,1,28,44368), Array (0,2,15,43856), Array (0,2,5,19296 ), Array (4,1,25,42352), Array (0,2,13,42352), Array (0,2,2,21088), Array (3,1,21,59696), Array (0,2,9,55632), Array ( 7,1,30,23208), Array (0,2,17,22176), Array (0,2,6,38608), Array (5,1,27,19176), Array (0,2,15,19152), Array (0,2,3,42192 ), Array (4,1,23,53864), Array (0,2,11,53840), Array (8,1,31,54568), Array (0,2,18,46400), Array (0,2,7,46752), Array ( 6,1,28,38608), Array (0,2,16,38320), Array (0,2,5,18864), Array (4,1,25,42168), Array (0,2,13,42160), Array (10,2, 2,45656), Array (0,2,20,27216), Array (0,2,9,27968), Array (6,1,29,44448), Array (0,2,17,43872), Array (0,2,6,38256), Array (5,1,27,18808), Array (0,2,15,18800), Array (0,2,4,25776), Array (3,1,23,27216), Array (0,2,10,59984), Array ( 8,1,31,27432), Array (0,2,19,23232), Array (0,2,7,43872), Array (5,1,28,37736), Array (0,2,16,37600), Array (0,2,5,51552 ), Array (4,1,24,54440), Array (0,2,12,54432), Array (0,2,1,55888), Array (2,1,22,23208), Array (0,2,9,22176), Array ( 7,1,29,43736), Array (0,2,18,9680), Array (0,2,7,37584), Array (5,1,26,51544), Array (0,2,14,43344), Array (0,2,3,46240) , Array (4,1,23,46416), Array (0,2,10,44368), Array (9,1,31,21928), Array (0,2,19,19360), Array (0,2,8,42416), Array ( 6,1,28,21176), Array (0,2,16,21168), Array (0,2,5,43312), Array (4,1,25,29864), Array (0,2,12,27296), Array (0,2,1,44368 ), Array (2,1,22,19880), Array (0,2,10,19296), Array (6,1,29,42352), Array (0,2,17,42208), Array (0,2,6,53856), Array ( 5,1,26,59696), Array (0,2,13,54576), Array (0,2,3,23200), Array (3,1,23,27472), Array (0,2,11,38608), array(11,1,31,19176), Array (0,2,19,19152), Array (0,2,8,42192), Array (6,1,28,53848), Array (0,2,15,53840), Array ( 0,2,4,54560), Array (5,1,24,55968), Array (0,2,12,46496), Array (0,2,1,22224), Array (2,1,22,19160), Array (0,2,10,18864 ), Array (7,1,30,42168), Array (0,2,17,42160), Array (0,2,6,43600), Array (5,1,26,46376), Array (0,2,14,27936), Array ( 0,2,2,44448), Array (3,1,23,21936), Array (0,2,11,37744), Array (8,2,1,18808), Array (0,2,19,18800), Array (0,2,8,25776) , Array (6,1,28,27216), Array (0,2,15,59984), Array (0,2,4,27424), Array (4,1,24,43872), Array (0,2,12,43744), Array ( 0,2,2,37600), Array (3,1,21,51568), Array (0,2,9,51552), Array (7,1,29,54440), Array (0,2,17,54432), Array (0,2,5,55888) , Array (5,1,26,23208), Array (0,2,14,22176), Array (0,2,3,42704), Array (4,1,23,21224), Array (0,2,11,21200), Array ( 8,1,31,43352), Array (0,2,19,43344), Array (0,2,7,46240), Array (6,1,27,46416), Array (0,2,15,44368), Array (0,2,5,21920 ), Array (4,1,24,42448), Array (0,2,12,42416), Array (0,2,2,21168), Array (3,1,22,43320), Array (0,2,9,26928),Array (7,1,29,29336), Array (0,2,17,27296), Array (0,2,6,44368), Array (5,1,26,19880), Array (0,2,14,19296), Array ( 0,2,3,42352), Array (4,1,24,21104), Array (0,2,10,53856), Array (8,1,30,59696), Array (0,2,18,54560), Array (0,2,7,55968 ), Array (6,1,27,27472), Array (0,2,15,22224), Array (0,2,5,19168), Array (4,1,25,42216), Array (0,2,12,42192), Array (   0,2,1,53584), Array (2,1,21,55592), Array (0,2,9,54560));

Here's how to use it:

<?php header ("Content-type:text/html;charset=utf-8"); $lunar =new lunar () $month = $lunar->convertsolartolunar (2013,07,08);//Convert the Gregorian calendar to the lunar echo ' <pre> '; Print_r ($month);

The printing results are as follows:
Array
(
[0] = 2013
[1] = May
[2] = Eve
[3] =
[4] = 5
[5] = 30
[6] = snake
[7] = 0
)
