PHP Solar to Lunar (lunar), lunar calendar method

Since a recent project designed to convert the Gregorian calendar to the lunar calendar to get the corresponding holiday algorithm, this is not very understanding, so the online search a lap. Yes, but also to find a relatively good PHP class, the realization of the Gregorian calendar to convert to the lunar calendar (lunar), the lunar calendar converted to the Gregorian algorithm, but also to obtain the Ganzhi annals, Zodiac, and the corresponding lunar calendar in Chinese, etc.

The specific class code is as follows:

	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 (0,2,4,11104), 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

Use the following methods:

<?php
Header ("Content-type:text/html;charset=utf-8");
$lunar =new lunar ();//http://www. alixixi.com/php-function/867.html
$month = $lunar->convertsolartolunar (2013,07,08);//convert Gregorian calendar to
lunar echo ' <pre> ';
Print_r ($month);

Print the results as follows:

[1] => May
